While `scap` does have support for Wayland and Windows, but haven't seen
screensharing work properly there yet. So for now just adding support
for X11 screensharing.
WIP branches for enabling wayland and windows support:
* https://github.com/zed-industries/zed/tree/wayland-screenshare
* https://github.com/zed-industries/zed/tree/windows-screenshare
Release Notes:
- Added support for screensharing on X11 (Linux)

No issue, as the functionality is currently not being used in Zed. This
is more of a GPUI improvement.
Currently, `keyboard_layout` and `on_keyboard_layout_change` are already
handled on macOS. This PR implements the same for X11 and Wayland.
Linux supports up to 4 keyboard layout groups (e.g., Group 0: English
US, Group 1: Bulgarian, etc). On X11 and Wayland, `event` provides a new
active group, which maps to the `layout_index`. We already store keymap
state from where we can get the current `layout_index`. By comparing
them, we determine if the layout has changed.

This changes the workspace/session serialization to also persist the
order of windows across restarts.
Release Notes:
- Improved restoring of windows across restarts: the order of the
windows is now also restored. That means windows that were in the
foreground when Zed was quit will be in the foreground after restart.
(Right now only supported on Linux/X11, not on Linux/Wayland.)

This PR consists of two main changes:
1. The first commit changes the `open` crate for opening URLs/paths for
the `OpenURI` desktop portal. This fixes the activation token not being
passed to programs (at least on KDE).
2. The second commit implements the window `activate()` API on Wayland.
This allows KWin and Mutter to show a visual indicator when the window
is requesting attention. (see
https://github.com/zed-industries/zed/issues/12557)

This changes the implementation of the X11 client to use `mio`, as a
polling mechanism, and a custom run loop instead of `calloop` and its
callback-based approach.
We're doing this for one big reason: more control over how we handle
events.
With `calloop` we don't have any control over which events are processed
when and how long they're processes for. For example: we could be
blasted with 150 input events from X11 and miss a frame while processing
them, but instead of then drawing a new frame, calloop could decide to
work off the runnables that were generated from application-level code,
which would then again cause us to be behind.
We kinda worked around some of that in
https://github.com/zed-industries/zed/pull/12839 but the problem still
persists.
So what we're doing here is to use `mio` as a polling-mechanism. `mio`
notifies us if there are X11 on the XCB connection socket to be
processed. We also use its timeout mechanism to make sure that we don't
wait for events when we should render frames.
On top of `mio` we now have a custom run loop that allows us to decide
how much time to spend on what — input events, rendering windows, XDG
events, runnables — and in what order we work things off.
This custom run loop is consciously "dumb": we render all windows at the
highest frame rate right now, because we want to keep things predictable
for now while we test this approach more. We can then always switch to
more granular timings. But considering that our loop runs and checks for
windows to be redrawn whenever there's an event, this is more an
optimization than a requirement.
One reason for why we're doing this for X11 but not for Wayland is due
to how peculiar X11's event handling is: it's asynchronous and by
default X11 generates synthetic events when a key is held down. That can
lead to us being flooded with input events if someone keeps a key
pressed.
So another optimization that's in here is inspired by [GLFW's X11 input
handling](b35641f4a3/src/x11_window.c (L1321-L1349)):
based on a heuristic we detect whether a `KeyRelease` event was
auto-generated and if so, we drop it. That essentially halves the amount
of events we have to process when someone keeps a key pressed.

TODO:
- [x] Finish GPUI changes on other operating systems
This is a largely internal change to how we report data to our
diagnostics and telemetry. This PR also includes an update to our blade
backend which allows us to report errors in a more useful way when
failing to initialize blade.

Since Wayland doesn't have a way for windows to activate themselves,
currently, when you click on a link in Zed, the browser window opens in
the background.
This PR implements the `xdg-activation` protocol to get an activation
token, which the browser can use to raise its window.
