This restores https://github.com/zed-industries/zed/pull/13943 which was
reverted in #13974 because it was possible to get in a state where focus
could not be restored on a window.
In this PR there's an additional change: `FocusIn` and `FocusOut` events
are always handled, even if the `event.mode` is not "NORMAL". In my
testing, `alt-tabbing` between windows didn't produce `FocusIn` and
`FocusOut` events when we had that check. Now, with the check removed,
it's possible to switch focus between two windows again with `alt-tab`.

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.

This change ensures that the event loop prioritizes enqueueing another
render or handling user input over executing runnables.
It's a subtle change as a result of a week of digging into performance
on X11. It's also not perfect: ideally we'd get rid of the intermediate
channel here and had more control over when and how we run runnables vs.
X11 events, but I think short of rewriting how we use an event loop,
this is good cost/benefit change.
To illustrate:
Before this change, it was possible to block the app from rendering for
a long time by just creating a ton of futures that were executed on the
"main" thread (we don't have a "main" thread on Linux, but we have a
single thread in which we run the event loop).
That was relatively easy to reproduce by opening the `zed` repository
and starting `rust-analyzer`: at some point `rust-analyzer` sends us so
many notifications, that are all handled in futures, that the event loop
is busy just working off the runnables, never getting to the events that
X11 sends us or our own timer to re-enqueue another render.
When you put print statements into the code to show when which event was
handled, you'd see something like this **before this change**:
```

```
Note the `lag: 56ms`: that's the difference between when we wanted to
execute the callback that enqueues another render and when it ran.
Longer lags are possible, this is just the first one I grabbed from the
logs.
Now, compare this with the logs **after this change**:
```

```
In-between many `runnable.run()` we'll always handle events.
So, in essence, what this change does is to introduce 2 priorities into
the X11 event queue:
- high: X11 events (user events, render events, ...), render tick, XIM
events, ...
- low: all async rust code
I've tested this with a debug build and release build and I think the
app now feels more responsive. It doesn't feel perfect still, especially
in the slow debug builds, but I couldn't observe 10s lockups anymore.
Since it's a pretty small change, I think we should go for it and see
how it behaves.
Thanks to @maan2003 this now also includes the same change to Wayland.

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

## Problem
in the situation `press right`, `press left`, `release right` the
following happens right now:
- `keypressed right`, `current_keysym` is set to `right`
- `keypressed left`, `current_keysym` is set to `left`
the repeat timer runs asynchronously and emits keyrepeats since
`current_keysym.is_some()`
- `keyreleased right`, `current_keysym` is set to None
the repeat timer no longer emits keyrepeats
- `keyreleased left`, this is where `current_keysym` should actually be
set to None.
## Solution
Only reset `current_keysym` if the released key matches the last pressed
key.

This PR adjusts our scrolling implementation to delay the generation of
ScrollWheel events until we receive a complete frame.
Note that our implementation is still a bit off-spec, as we don't delay
any other kind of events. But it's been working so far on a variety of
compositors and the other events contain complete data; so I'll hold off
on that refactor for now.

With the recent Linux rewrite, I attempted to simplify the number of
wrapper structs involved in the Linux code, following the macOS code as
an example. Unfortunately, I missed a vital component: pointers to the
platform state, held by platform data structures. As we hold all of the
platform data structures on Linux, this PR reintroduces a wrapper around
the internal state of both the platform and the window. This allows us
to close and drop windows correctly.
This PR also fixes a performance problem introduced by:
https://github.com/zed-industries/zed/pull/10343, where each configure
request would add a new frame callback quickly saturating the main
thread and slowing everything down.
Release Notes:

This fixes certain shortcuts/motions on X11 like in vim mode "v i )",
where previously zed would interpret it as "v i SHIFT )" due to the x11
backend emitting key press events for modifier keys even though other
platforms like Wayland don't. This also adds support for
ModifiersChanged events to X11
Release Notes:
- Fixed vim motions like "v i )" not working on X11
([#10199](https://github.com/zed-industries/zed/issues/10199)).
This puts the Linux platform implementation at a similar code style and
quality to the macOS platform. The largest change is that I collapsed
the `LinuxPlatform` -> `[Backend]` -> `[Backend]State` ->
`[Backend]StateInner` to just `[Backend]` and `[Backend]State`, and in
the process removed most of the `Rc`s and `RefCell`s.
