The EGL_WL_create_wayland_buffer_from_image is still used in WPE WebKit.
There is work in progress to continue adoption of DMA-BUF usage inside
WebKit which will eventually render the extension unneeded; but in the
meantime an update to a version of Mesa without the extension would
render applications using WPE WebKit unusable.
This reverts commit a3418105b9.

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 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.

I'm not sure why I picked html_extra_path instead, as it's meant for
slightly less directly related files than what html_static_path is for.
So let's switch. It shouldn't make much of a real-world difference, but
should make it a bit easier to understand what this is about.
