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.
