Although the error rate of timestamp tick->ns conversion is very small
(3e-5), some profiling scenarios, such as CPU/GPU timestamp calibration
on Windows, require absolutely accurate timestamps.
Add new toggle to resolve timestamps to ticks for those cases where zero
error is required.
Add an end2end test for GPU timestamp calibration on D3D12 backend.
Disable timestamp period calculation on Device when the
DisableTimestampQueryConversion is enabled.

- Don't use for..in since some crashes show that NSFastEnumeration
in those loops is doing something wrong.
- Check that the receiver actually supports the selector before
calling it. Crashes indicate an unrecognized selector is being
used.
- Add a ref to MTLCounterSet to be sure it is not somehow freed
between when it is stored, and when we use it as the receiver for
[MTLCounterSet counters].

Introduces the majority of the logic associated with enabling
multiplanar external textures. Removes most backend logic associated
with external textures in favor of expanding them into their components
in the frontend. Includes a basic e2e test demonstrating multiplanar
YUV-to-RGB conversion.
