Daniel Stone a3418105b9 egl/wayland: Remove EGL_WL_create_wayland_buffer_from_image
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.
