drm/xe: Add uAPI to query GuC firmware submission version
Due to a bug in GuC firmware, Mesa can't enable by default the usage of
compute engines in DG2 and newer.
A new GuC firmware fixed the issue but until now there was no way
for Mesa to know if KMD was running with the fixed GuC version or not,
so this uAPI is required.
It may be expanded in future to query other firmware versions too.
This is querying XE_UC_FW_VER_COMPATIBILITY/submission version because
that is also supported by VFs, while XE_UC_FW_VER_RELEASE don't.
i915 uAPI: https://patchwork.freedesktop.org/series/129627/
Mesa usage: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25233
v2:
- fixed drm_xe_query_uc_fw_version documentation
- moved branch_ver as the first version number
