Converting mesa/demos to Meson

[Erik Faye-Lund]

OK, and now with over a month and a half since the release of mesa-
demos 8.5.0 which deprecated the other build systems, I think it might
be about time to remove the cmake and autotools support.

I've had up an MR for a while for this, so please direct any objections
in this direction:

https://gitlab.freedesktop.org/mesa/demos/-/merge_requests/74

If I don't hear any objections in a few weeks, I plan on merging that
change.
