DRM syncobjs always let you wait repeatedly on them, so we can set the
flag in the core instead of having each driver override it once they try
to enable the emulated timeline semaphores.

The v3dv kernel driver doesn't support timelines yet but we want
threaded submit and that requires WAIT_PENDING. Fortunately, it should
never sit in this loop for long in practice. The primary use-case is
sorting out dependencies and these checks will always trivially succeed
for non-shared semaphores because v3dv only has a single queue.

Instead of having a bunch of const vk_sync_type for each permutation of
vk_drm_syncobj capabilities, have a vk_drm_syncobj_get_type helper which
auto-detects features. If a driver can't support a feature for some
reason (i915 got timeline support very late, for instance), they can
always mask off feature bits they don't want.
