Marcin Slusarz 1dfa2fd98f drm/panthor: extend timestamp query with flags
Flags now control which data user space wants to query,
there is more information sources, and there's ability
to query duration of multiple timestamp reads.

New sources:
- CPU's monotonic,
- CPU's monotonic raw,
- GPU's cycle count

These changes should make the implementation of
VK_KHR_calibrated_timestamps more accurate and much simpler.
