Drop the limitation to 24 or 30 bit configs. It was an abritrary
compromise to usually give apps what they wanted, but now we are about
to get a clean solution for alpha-blending on X11.

EGL 1.5 specification requires to not match on EGL_NATIVE_VISUAL_ID.
EGL_MESA_x11_native_visual_id extension allows us to remove this
restriction for X11, where we need to match EGL_NATIVE_VISUAL_ID to find
visuals which allow blending.
The reasoning is that on X11, compositors use the visual as "magic bit"
to decide whether to alpha-blend surface contents.
Unlike on most (all?) other windowing systems, requesting an alpha channel
for the config alone does not already imply blending on the compositor
level.
Thus, in order to allow clients to explicitly request configs with
"magic bit" and, similar to GLX, to order configs in a way so clients
not requesting alpha-blending do not get it by accident, do match
visual ids.
Note that one consequence of this is that more configs get
reported to clients.

This ensures that alpha-blended windows are at the bottom of the visuals
list, so they don't get picked up accidentally.

Since commit 7d9ea77b45 ("glx: add automatic zink fallback loading between hw
and sw drivers"), zink could be tried as a fallback. It'd better silence
if the zink loading is implicit and on fail as what commit 4cc975c6e9 ("glx: silence
more implicit-load zink errors") has done. But there seems to be one
left bebind, which is spit when building swrast but no zink with -Dglx=dri.

I'm not sure why zink would want dri2 here instead of kopper,
I'm sure it's some side effect of something else, let zink
use the kopper paths.

This is achieved by the following steps:

#ifdef DEBUG => #if MESA_DEBUG
This is done by replace in vscode
excludes

These are safe because those files should keep DEBUG macro is already excluded;
and not directly replace DEBUG, as we have some symbols around it.
Use debug or NDEBUG instead of DEBUG in comments when proper
This for reduce the usage of DEBUG,
so it's easier migrating to MESA_DEBUG
These are found when migrating DEBUG to MESA_DEBUG,
these are all comment update, so it's safe
Replace comment /* DEBUG */ and /* !DEBUG */ with proper /* MESA_DEBUG */ or /* !MESA_DEBUG */ manually
DEBUG || !NDEBUG -> MESA_DEBUG || !NDEBUG
!DEBUG && NDEBUG -> !(MESA_DEBUG || !NDEBUG)

This extension was originally intended to complement
EGL_WL_bind_wayland_display.
The idea behind bind_wayland_display was that libEGL.so on the server
side could register Wayland extensions for libEGL.so on the client side
to use to create buffers, with eglQueryWaylandBufferWL being used to
query the buffer properties, and EGL_WAYLAND_BUFFER_WL added as an
EGLImage target for texturing.
eglCreateWaylandBufferFromImageWL was then to be used for nested
compositors to perform passthrough: it would take an EGLImage created by
the magical libEGL secret handshake, and make it usable in the parent
compositor by doing the same secret handshake again.
Since that original idea, we've just standardised dmabuf across the
Wayland ecosystem instead. The last known user of this extension was a
sample client in the Weston tree, which was broken quite some years ago
and never ported to the Meson build system when we moved.
Given it won't affect anyone, let's just remove this extension so no-one
thinks it would be a good idea to use it.
