Follow-up to #24797
This PR ensures some cursor styles do not change for draggable elements
during dragging. The linked PR covered this on the higher level for
draggable divs. However, e.g. the pane divider inbetween two editors is
not a draggable div and thus still has the issue that the cursor style
changes during dragging. This PR fixes this issue by setting the hitbox
to `None` in cases where the element is currently being dragged, which
ensures the cursor style is applied to the cursor no matter what during
dragging.
Namely, this change fixes this for
- non-div pane dividers
- minimap slider and the
- editor scrollbars
and implements it for the UI scrollbars (Notably, UI scrollbars do
already have `cursor_default` on their parent container but would not
keep this during dragging. I opted out on removing this from the parent
containers until #30194 or a similar PR is merged).

This change is used to solve the problem of not being able to respond
correctly in two-layer scrolling (in different directions). This is a
common practical requirement.
As in the example, in actual use, there may be a scene with a horizontal
scroll in a vertical scroll. Before the modification, if we scroll up
and down in the area that can scroll horizontally, it will not respond
(because it is blocked by the horizontal scroll layer).

This change may cause many side effects, causing some scrolling details
to be different from before, and more testing and analysis are needed.
I have tested some existing scenarios of Zed (such as opening the Branch
panel on the Editor and scrolling) and it seems to be correct (but it is
possible that I don’t know some interaction details). Here, the person
who added this line of code before needs to evaluate the original
purpose.

The before version GPUI used `Cancel` for cancel text, if we use
non-English text (e.g.: "取消" in Chinese), then the press `Esc` to cancel
will not work.
So this PR to change it by use `PromptButton` to instead the `&str`,
then we can use `PromptButton::cancel("取消")` for the `Cancel` button.
Run `cargo run -p gpui --example window` to test.

tl;dr: This adds `.block_mouse_except_scroll()` which should typically
be used instead of `.occlude()` for cases when the mouse shouldn't
interact with elements drawn below an element. The rationale for
treating scroll events differently:
* Mouse move / click / styles / tooltips are for elements the user is
interacting with directly.
* Mouse scroll events are about finding the current outer scroll
container.
Most use of `occlude` should probably be switched to this, but I figured
I'd derisk this change by minimizing behavior changes to just the 3 uses
of `block_mouse_except_scroll`.
GPUI changes:
* Added `InteractiveElement::block_mouse_except_scroll()`, and removes
`stop_mouse_events_except_scroll()`
* Added `Hitbox::should_handle_scroll()` to be used when handling scroll
wheel events.
* `Window::insert_hitbox` now takes `HitboxBehavior` instead of
`occlude: bool`.
- `false` for that bool is now `HitboxBehavior::Normal`.
- `true` for that bool is now `HitboxBehavior::BlockMouse`.
- The new mode is `HitboxBehavior::BlockMouseExceptScroll`.
* Removes `Default` impl for `HitboxId` since applications should not
manually create `HitboxId(0)`.

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This PR fixes several possible memory leaks due to loading images in
markdown files and the image viewer, using the new image cache APIs
TODO:
- [x] Ensure this didn't break rendering in any of the affected
components.
Release Notes:
- Fixed several image related memory leaks
cc: @sunli829 @huacnlee @probably-neb
I really liked the earlier PR, but had an idea for how to utilize the
element state so that you don't need to construct the cache externally.
I've updated the APIs to introduce an `ImageCacheProvider` trait, and
added an example implementation of it to the image gallery :)
Release Notes:
- N/A
Closes#27414
`ImageCache` is independent of the original image loader and can
actively release its cached images to solve the problem of images loaded
from the network or files not being released.
It has two constructors:
- `ImageCache::new`: Manually manage the cache.
- `ImageCache::max_items`: Remove the least recently used items when the
cache reaches the specified number.
When creating an `img` element, you can specify the cache object with
`Img::cache`, and the image cache will be managed by `ImageCache`.
In the example `crates\gpui\examples\image-gallery.rs`, the
`ImageCache::clear` method is actively called when switching a set of
images, and the memory will no longer continuously increase.

This PR adds a new `PlatformKeyboardLayout` trait with two methods:
`id(&self) -> &str` and `name(&self) -> &str`. The `id()` method returns
a unique identifier for the keyboard layout, while `name()` provides a
human-readable name. This distinction is especially important on
Windows, where the `id` and `name` can be quite different. For example,
the French layout has an `id` of `0000040C`, which is not
human-readable, whereas the `name` would simply be `French`. Currently,
the existing `keyboard_layout()` method returns what's essentially the
same as `id()` in this new design.
This PR implements the `name()` method for both Windows and macOS. On
Linux, for now, `name()` still returns the same value as `id()`.

Earlier, I merged #24723
Before merging it, I made a change that was incorrect and fast followed

Fix this long-standing issue so that we can support Link hover colors.
And renamed `text_layout` example to `text_style`.
---
I spent some time studying the process of this text style change and
found it a bit complicated.
At first, I thought there was a problem with refine and it was not
passed properly. After changing it, I found that it was not the problem.
Then I found that it was because `TextRun` had already stored the
`color`, `background`, `underline`, `strikethrough` in TextRun in the
`request_layout` stage. They area calculate at the `request_layout`
stage, but request_layout stage there was no `hitbox`, so the hover
state was not obtained.
```bash
cargo run -p gpui --example text_style
```

Closes#4461
Take 2 on https://github.com/zed-industries/zed/pull/25040.
Fixes panic caused due to using `setHiddenUntilMouseMoves` return type
to `set` cursor on macOS.
Release Notes:
- Now cursor hides when the user is typing in editor. It will stay
hidden until it is moved again. This behavior is `true` by default, and
can be configured with `hide_mouse_while_typing` in settings.

I will try to do some test.
For example: With a threshold for the hold number of caches in

- [x] PatternDash
- [x] `pattern_horizontal_dash` & `pattern_vertical_dash`
- [x] Metal dash shader
- [x] Blade dash shader
- [x] Update ui::Divider to use new pattern
---
This PR introduces proper dashed dividers using the new `PatternDash`
background shader.

Before this we were using 128 elements to create a dashed divider, which
is both expensive, and would not scale beyond a certain size. This
allows us to simplify the divider element as well.
Changes:
- Adds `BackgroundOrientation` to `gpui::color::Background` to allow
specifying a direction for a pattern
- Adds the PatternDash pattern variant
- Updates `ui::Divider`'s dashed variants to be more efficient
Misc:
- Documents the `ui::Divider` component
- Treat `.metal` files as `C` in the Zed project until we get some metal
syntax highlighting.
Release Notes:
- N/A
TODO:
- [x] Add BackgroundTag::PatternSlash
- [x] Support metal slash pattern fills
- [x] Support blade slash pattern fills
---
Adds support for a new background type in gpui, `pattern_slash`.
Usage:
```rust
div().size(px(56.0)).bg(pattern_slash(gpui::red()))
```
This will create a 56px square with a red slash pattern fill.
You can run the pattern example with `cargo run -p gpui --example
pattern`:

---
After talking with @as-cii at length about how we want to support
patterns in gpui, we decided for now we'll simply add a new
BackgroundTag specific to this pattern.
It isn't the best long term plan however – we'll likely want to
introduce the concept of a `Fill` at some point so we can have
`Fill::Solid`, `Fill::Gradient(LinearGradient)`, etc in the future.
The pattern is designed to seamlessly tile vertically for elements of
the same height. For example, for use in editor line backgrounds:
