- Recently we're missing some drawings as we disabled flushing cached images in frame callback. Let's enable it again and make sure we don't flush the drawings between Lock()/Commit() compositor calls which is controlled by mBufferCommitAllowed.
- When we draw directly to wl_buffer, flush all cached drawings we have or clear them if there's fullscreen update. It prevents potential rendering of cached images over unrelevant buffer content.
- Flush cached images when wl_buffer is detached by wayland compositor. It allows to paint delayed drawings and ensures they won't stay in the queue infinitely.
- Use mBufferPendingCommit to indicate that the WaylandBuffer contains updates from gecko which has not been submitted to wayland compositor yet. Allows delated commit handlers (frame callback, delayed commit and when wl_buffer is detached) to send WaylandBuffer content to wayland compositor.
- Record time of last finished commit to mLastCommitTime and throws warning when wayland compositor does not release wl_buffer in 200ms.
- Use wl_display_sync() to synchronize wl_display events. Wait for events from wl_display until all pending events are processed before we start drawing at WindowSurfaceWayland::Lock(). There may wl_buffer release event waiting which releases wl_buffer for rendering.
- Don't use XMost()/YMost() to get drawing area size.
- Remove mDisplayThreadMessageLoop as it's no longer used.

Image cache mode can be set by widget.wayland_cache_mode.
- widget.wayland_cache_mode = 0 (or missing):
Cache and clip all drawings, default. It's slowest
but also without any rendered artifacts.
- widget.wayland_cache_mode = 1:
Cache drawing only when back buffer is missing. May produce
some rendering artifacts and flickering when partial screen update
is rendered.
- widget.wayland_cache_mode = 2:
Don't cache anything, draw only when back buffer is available.
Suitable for fullscreen content only like fullscreen video playback and
may work well with dmabuf backend.

Lazilly create nsWaylandDisplay objects and remove them at Firefox quit.
nsWaylandDisplay objects should stay as global objects and don't be created/released.
The creation/removal wastes resources on server side as the wl_registry objects at nsWaylandDisplay has to be stored at server
side and can't be removed until firefox ends [1] anyway.
Also the removed nsWaylandDisplay causes crashes when display
topology changes due to the global nature of the wl_registry.
