Earlier versions of gl2ext.h defined the GL_EXT_unpack_subimage tokens
without the _EXT suffix. That's been fixed and we're using the _EXT
tokens now, but just in case we're using an older, broken header, define
the _EXT tokens manually.
In cases where the GPU can natively handle certain YUV formats,
eglQueryWaylandBufferWL() can return the value EGL_TEXTURE_EXTERNAL_WL
and the compositor will treat the buffer as a single egl-image-external.

v1: original
v2: rename EGL_TEXTURE_EXTERNAL_OES -> EGL_TEXTURE_EXTERNAL_WL and query
for the extension
v3: fix build without updated mesa headers, if EGL_TEXTURE_EXTERNAL_WL
#define is missing from older mesa headers.
v4: resend without missing parts

This is a workaround for platforms, whose EGL headers miss the
definitions for EGL_WL_bind_wayland_display.
