Due to: https://github.com/zed-industries/zed/issues/9985 and an
abundance of caution, I'm reverting the image and svg rendering updates
for now until we can debug the issue. cc: @niklaswimmer
Release Notes:
- N/A
Updated version of #9741 with fixes for the problems raised in #9774. I
only verified that the images no longer look blueish on Linux, because I
don't have a Mac.

This PR updates the `TextSystem` on macOS to allow loading the "Segoe
Fluent Icons" font.
We're using this font in the Storybook to render the `TitleBar` as it
would appear on Windows despite us running it on macOS. This is to make
things easier for iterating on UI design without needing to test on each
individual platform.
However, the "Segoe Fluent Icons" font does not have a glyph for the `m`
character, causing it to run afoul of a precautionary check added in
#4029, which ultimately results in the font not being loaded (and thus
rendering as a missing glyph).
We work around this by simply ignoring this check if the font we're
trying to load is specifically "Segoe Fluent Icons".
I think longer-term we'll need to revisit the behavior in the editor
that is causing the panics when the `m` glyph is missing from the font,
but that's a problem for a different day.

Note that you currently need to install the "Segoe Fluent Icons" font
yourself—either installing it globally or placing the `.ttf` file in the
`assets/fonts` directory—in order to see the icons rendered. I'd like to
look into getting this, but there are restrictions on the distribution
of the font on non-Windows platforms that will need to be followed.

Release Notes:
- Separated Linux platform and X11-specific code, so that we can add
Wayland support now.

The fonts we embed in Zed binary (Zed Sans & Zed Mono) weigh about 30Mb in total and we are cloning them several times during startup and loading of embedded assets (once explicitly in Zed and then under the hood in font-kit). Moreover, after loading we have at least 2 copies of each font in our program; one in .rdata and the other on the heap for use by font-kit.
This commit does away with that distinction (we're no longer allocating the font data) and slightly relaxes the interface of `TextSystem::add_fonts` by expecting one to pass `Cow<[u8]>` instead of `Arc<Vec<u8>>`. Additionally, `AssetSource::get` now returns `Cow<'static, [u8]>` instead of `Cow<'self, [u8]>`; all existing implementations conform with that change.
Note that this optimization takes effect only in Release builds, as the library we use for asset embedding - rust-embed - embeds the assets only in Release mode and in Dev builds it simply loads data from disk. Thus it returns `Cow<[u8]>` in it's interface. Therefore, we still copy that memory around in Dev builds, but that's not really an issue.
This patch makes no assumptions about the build profile we're running under, that's just an intrinsic property of rust-embed.
Tl;dr: this should shave off about 30Mb of memory usage and a fair chunk (~30ms) of startup time.
Release Notes:
- Improved startup time and memory usage.
During layout of EditorElement we use 'm' character from current font to calculate sizes, panicking with fonts that do not have that character (e.g. Arabic fonts). It's not really EditorElement's fault, as it assumes that the font it's dealing with is gonna have that character available.
To prevent a crash, I added validation while loading a family that a given font contains the glyphs we're gonna use down the line.
I essentially went through the publicly exported items and marked these
that are e.g. leaky reexports as pub(crate). I expect that'd be done on
Tuesday anyways.
