Cycles X: Make shadow catcher approximation more explicit

Only affects internal API, the user level stays unchanged.

Just replacing some implicit decisions in a generic code path with
something what is more explicit.

Cycles X: Move actual pass type logic outside of pass accessor

Keeps the accessor free from tricky logic, allowing to make more
comprehensive decisions based on various scene settings.

Merge branch 'master' into cycles_texture_cache

Add TODO to improve is_render_registered

Add TODO for get_area_of_interest parameter overloading

Add TODO to remove execute_work workaround.

USD import: convert from nits on by default.

Enabling the Convert Light Units from Nits option
by default.

Use mutex lock instead of atomics

Add TODO to implement MemoryBuffer get_size()

Cycles: Writing texture cache stats through VLOG not std::cout.

USD import: format fixes.

Merging latest from branch nv-usd-importer.

USD import: creater readers for untyped prims.

Added code to handle less common case where the USD prim
has no type specified (seen in some legacy USDs). We still
want to import such prims in order to access their descendents.

Add support for float2, float3, color, and instance columns

Bulk commit of current override recursive resync.

Mostly to get test builds for artists, code seems to be working, but
final commit will need to be split, and there is some cleanup to be done
first anyway.

Cycles X: Implement early cancel in GPU rendering

Allow the GPU rendering to stop rendering before all scheduled paths
has been terminated. This significantly lowers latency of the viewport
navigation.

With some files from the Sprites Fright project the time spend in the
`PathTrace::cancel()` is reduced from 0.6 to below 0.01 sec.
