Some events (especially from xinput) cannot be cleanly mapped to a window.
Instead of requiring every event to come with a `Window` reference, move
the window into those events, that have one.
The current code always acquires the buffer it just submitted,
which results in always rendering to a buffer with age "1", although
its contents are older, because the currently held buffer is already
submitted, just not to the swapchain. When it finally is submitted
its age is again set to 1, the other gets its correct age (but too late)
and the circle is repeated again. So lets fix that.
Refactors the `X11Surface` to use the `Swapchain` internally,
which gives us a buffer age implemenation, which we can then use
to change the `Present` struct of the X11 backend to provide age
values to the user.
This change also merged the `Present` struct into the surface
because submits should now happen explicitly via a new `submit`-call
instead of being submitted implicitly on drop.
This allows the buffer to be discarded if rendering fails.
More specifically, this introduces a way to query the available EGL devices on a system, `EGLDevices::enumerate`.
Also this introduces a way to get the `EGLDevice` used by an `EGLDisplay`, `EGLDevice::device_for_display`

Currently keycodes are always converted using xkbcommons
`State::key_get_one_sym` function. This may be not what the compositor
wants, e.g. if it represents keybindings with explicit modifiers.
Applying Shift in this case changes the sym, making it necessary for
the compositor to *undo* this transformation, which is hard or even
impossible and very unnecessary, when we have all the necessary
information in smithay.
Therefor this commit replaces the `Keysym` argument of the filter
closure with a `KeysymHandle`, which allows for different variants of
keysyms to be received. Modified (as previously), unmodified or even
as a raw keycode.
The previous commit added a new worker thread. This thread might sit in
wait_for_event() indefinitely even after the X11Source was dropped. This
is because nothing guarantees that an X11 event will come in "soonish".
And only then would the thread notice that its main thread is gone.
This commit cleans that up by having X11Source explicitly wake up the
event thread and wait for it to exit in its Drop implementation.

x11rb caches X11 events internally. This cache is used when waiting for
the reply of a request and an event is received first. This cache is
however also used when sending a request, because the X11 client may
never block and stop reading while writing a request. Doing so could
cause a deadlock with the X11 server.
Thus, this commit changes X11Source to spawn a thread internally. This
thread calls wait_for_event() in a loop and uses a calloop channel to
forward these events to the main loop. x11rb's RustConnection internally
uses a ConditionVariable to make sure this thread will wake up when
needed.
