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.
