This commit ensures that sync objects are deleted when they are replaced.

5d5e4ede1a [client] egl: use new EGL damage count semantics 
After the damage queue PR, EGL damage count 0 means no change, and -1 means
invalidate the entire window. However, several other places have different
semantics, and we are not handling them correctly:

1. KVMFR uses 0 to signal invalidating the entire frame, so if we receive 0
   rectangles in egl_on_frame, we should set damage count to -1.
2. The damage overlay treated 0 as full damage, which is now incorrect. This
   is fixed, and now it treats 0 as no update, and -1 as full damage.

df0397b10b [client] imgui: track last rectangles for overlays 
This is necessary in case overlays change size. When this happens, we must
damage the larger of the overlays' rectangles this frame and last frame.
This erases the overlay from where it is no longer appears.

In order to do this, we must keep track of the rectangles for every overlay
with no exception. We cannot short-circuit the generation of rectangles if
we run out of buffer space, and we must allocate space for MAX_OVERLAY_RECTS
rectangles for every frame. Otherwise, we will not know where to erase the
overlay if it disappears.

The OpenGL renderer backend should not depend on any particular
implementation of OpenGL, as it's used by both X11 and Wayland.

563ad18f4e [client] egl: improve cursor damage logic 
1. Use atomics and return exact cursor positions from egl_cursor_render
   to avoid race conditions between cursor render and update.
2. Instead of messing with lastCursorValid in various overlays, simply use
   the hasOverlay/hadOverlay logic for cursor damage. This simplifies the
   logic greatly.

As a result, I believe all cursor-related artifacts are fixed.

Note to reviewer: as atomic_init and atomic_store are implemented as macros,
it is currently not possible to pass structs as compound literals due to the
comma being interpreted as an argument separator by the preprocessor.

7c872d2d9e [client] egl: properly use OpenGL ES 
Instead of using the desktop <GL/gl.h>, we properly use the OpenGL ES 3.x
headers. Also, we now use GL_EXT_buffer_storage for MAP_PERSISTENT_BIT_EXT
and MAP_COHERENT_BIT_EXT as the core versions are only available in desktop
OpenGL 4.4. Similarly, we need GL_EXT_texture_format_BGRA8888 for GL_BGRA_EXT
as GL_BGRA is desktop-only.
