drm: check syncobj timeline support before advertising protocol (#11117)

Browse source 
Prevents crashes on systems where DRM driver lacks syncobj timeline
support (e.g., Apple Silicon with Honeykrisp driver). Applications
like Zed and WezTerm would crash with 'Timeline failed importing'
when trying to use explicit sync.

Fixes #8158 #8803
