backend/x11: create per-window present event contexts

Browse source 
The Present protocol states:

> An event context is associated with a specific window; using an existing
> event context with a different window generates a Match error.

Instead of a global event context, use a per-window event context to fix
this error:

    [backend/x11/backend.c:608] X11 error: op Present (SelectInput), code Match (no extension), sequence 63, value 4194307

Closes: https://github.com/swaywm/wlroots/issues/2577
