Associates every window with its own refresh event. Removes the use of
X11 present.
Alternative to #8592.
Instead of doing the rendering on idle and then involving a hack for
polling X11 events, this PR just tries to do the rendering inside the
main loop. This guarantees that we continue to poll for events after the
draw, and not get screwed by the driver talking to X11 via the same file
descriptor.
Release Notes:
- N/A
This PR unifies the event loop code for Wayland and X11. On Wayland,
blocking dispatch is now used. On X11, the invisible window is no longer
needed.

With this change, interaction with Zed is actually real-time and usable

The gist of it is - trying to process all of the input events before
rendering anything.

**Note**: this can be further improved in a follow-up.
Currently, once the input and runnables are processed, we'd try to draw
+ render a frame.
Presentation starts with acquiring a new frame. We currently have FIFO
presentation method, so acquiring a frame is blocking on that swapchain
image to become available. As the result, presentation takes around 16
ms, most of which is just busy wait.
Ideally, we'd be able to process more input in this time frame, instead.
**Note2**: it's a bit laggy in Debug for me, but that's just because of
the extra-long `draw` times, which is unrelated to rendering (or
platform support, for the matter). I'm curious how come on MacOS the
`draw()` times in Debug are more modest.
[Profiling](https://crates.io/crates/profiling) crate allows easy
integration with various profiler tools. The best thing is - annotations
compile to nothing unless you request a specific feature.
For example, I used this command to enable Tracy support:
```bash
cargo run --features profiling/profile-with-tracy
```
At the same time I had Tracy tool open and waiting for connection. It
gathered nice stats from the run:

Alternative to #7758, which doesn't involve adding a new trait method
`request_draw`.
Somehow, my whole screen goes blinking black with this when moving the
window, so not ready for landing.

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