[USD] Integrate "tinyusdz" project (#5628)

* Squash development commits for PR

* Fix failing build on armeabi-v7a via android NDK

* Update with blendshape support

* Migrate to auto-cloning and patching tinyusdz (instead of manually copying files)

* Update to latest rendermesh-refactor branch commit

* Remove tracked file

* Update to use recent commit to "dev" branch

"rendermesh-refactor" was merged to "dev" around 9 May 2024 but merge
was not obvious from commit messages

* Add UNUSED() macro

(cherry picked from commit d89fe8f034c353cc5cc5b3ac78cd8845e006de38)

* Update tinyusdz branch

* Prevent per-ABI (x86, x86_64 etc) clone on android

* Add verbose logging cmake option

* Fix macro and patch

* Address compiler warnings

* Address compiler warnings

* Address compiler warnings

* Attempt prevent re-clone/re-patch once downloaded by any ABI build

* Disable tinyusdz clone/build by default

assimp github PR auto-CI checks clone/build the tinyusdz code, and reject PR
due to compiler warnings in the 3rd party external tinyusdz project
