vulkan: Add VK_EXT_calibrated_timestamps extension (radv and anv) [v5]
Offers three clocks, device, clock monotonic and clock monotonic
raw. Could use some kernel support to reduce the deviation between
clock values.
v2:
Ensure deviation is at least as big as the GPU time interval.
v3:
Set device->lost when returning DEVICE_LOST.
Use MAX2 and DIV_ROUND_UP instead of open coding these.
Delete spurious TIMESTAMP in radv version.

v4:
Add anv_gem_reg_read to anv_gem_stubs.c
Suggested-by: Jason Ekstrand <[email protected]>
v5:
Adjust maxDeviation computation to max(sampled_clock_period) +
sample_interval.
