mesa-demos: update 8.5.0 -> 9.0.0

Browse Source 
The new version is in a location that isn't discoverable
by upstream version checks, and so has been overlooked for a while.

Drop patches:
0001-mesa-demos-Add-missing-data-files.patch
(backport)
0004-Use-DEMOS_DATA_DIR-to-locate-data-files.patch
(very old patch rejected by upstream as not necessary and not making sense:
https://gitlab.freedesktop.org/mesa/demos/-/issues/9 )

Disably wayland for now due to libdecor dependency,
adjust other feature dependencies as needed.

(From OE-Core rev: 59a9e96fa43e18af932cec7c2f1a36d9fcafff94)

Subject: [PATCH 1/9] mesa-demos: Add missing data files.
Add some data files that are present in the git repository:
http://cgit.freedesktop.org/mesa/demos/tree/?id=mesa-demos-8.1.0
but not in the release tarball
ftp://ftp.freedesktop.org/pub/mesa/demos/8.1.0/mesa-demos-8.1.0.tar.bz2
