USD: use a struct USDMeshData to group mesh data for USD export

Disable debug extension on Windows

Unfortunately, enabling XR_EXT_debug_utils crashes instance creation
with the Windows Mixed Reality runtime. Maybe I'm doing something wrong,
for now, just disable it.

General minor fixes and cleanup

* Initialize all class member variables
* Add version to runtime name printing
* Separate functionality code from debug prints
* Improve code structure using Doxygen groups
* Make accessors const functions
* Add (Doxygen) comments
* Naming
* Reorder functions

use StringMap everywhere

Fix T66604: Cycles bake crash on specific scene with volume

The issue was caused by un-initialized local storage for volume
intersection hits which are supposed to be stored in per-thread
KernelGlobals.

Fix is to make thread_shader() be the same as thread_render() in
respect of KernelGlobals.

Fix T66672: auto and manual texture space affected by modifiers

It should be based on the mesh bounds before modifier stack evaluation, but
some modifiers were causing it to be recomputed. The flag to disable texture
space recomputation was not preserved through modifier evaluation.
