intel: Move anv_gem_supports_syncobj_wait to common code.
This will let me use this in iris. We leave the existing anv function for anv_gem_stubs.c faking, but move the contents to a helper in a new src/intel/common/gen_gem.c file. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3802>
