This series adds Xe-specific timeline syncobj coverage for both
xe_exec and xe_vm_bind.

The main motivation is the xe_exec input case: waiting on an older
completed timeline point after the same syncobj has already advanced to
a later point. That is the shape that exposed the historical xe_exec
NULL-fence regression.

The series is split by interface:

 - patch 1 adds the exec coverage, including the regression-oriented
   completed-point input case and a timeline output case
 - patch 2 adds matching vm_bind coverage for the same timeline syncobj
   behavior

Validation summary:

 - on a fixed kernel, all four subtests pass
 - on an intentionally faulty kernel matching the old behavior, both
   vm_bind subtests pass, xe_exec output passes, and only the xe_exec
   completed-point input subtest fails

v2:
 - Switch from drmGetCap() to igt_has_drm_cap() as per Kamil Konieczny's
   review feedback
