drm/xe/oa/uapi: Query OA unit properties
Implement query for properties of OA units present on a device.
v2: Clean up reserved/pad fields (Umesh)
Follow the same scheme as other query structs
v3: Skip reporting reserved engines attached to OA units
v4: Expose oa_buf_size via DRM_XE_PERF_IOCTL_INFO (Umesh)
v5: Don't expose capabilities as OR of properties (Umesh)
v6: Add extensions to query output structs: drm_xe_oa_unit,
drm_xe_query_oa_units and drm_xe_oa_stream_info
v7: Change oa_units[] array to __u64 type
