gdk_wayland_gl_context_realize properly checks for GLES and uses
eglBindAPI with the proper API, but before that init is always called
with regular GL interface which is not implemented for many embedded
devices.
This was fixed in GTK 4 with commit 482845b02705 ("wayland: Remove
initial GL API bind"), but that commit cannot easily be applied because
the current version queries some GL properties during init so we would
need to backport more for it to be applicable.
This patch takes the minimal approach of initializing GLES context,
allowing the gtk3 demo OpenGL test (and real applications) to work
when GDK_GL=gles is set.
