material is almost no longer used in the code base and the
few remaining references makes it confusing when looking at parts
of the codebase. So rename the rest as well.
Note that this renames a DeformEffect property and the only extension
making use of it doesn't use the property so i think it is okay to do
so without deprecating the old property for a few releases

Group all the three config files from clutter/cogl/meta into one
and also remove unnused configurations and replace duplicated ones
This also fixes Cogl usage of HAS_X11/HAS_XLIB to match the expected
build options
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3368>
In cogl use cogl-config.h and in clutter use clutter-build-config.h. We
can't use clutter-config.h in clutter because its already used and
installed.
