X11: Don't emit keypress events for modifiers (#10271)

Browse Source 
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)).
