Anthony Roberts 7e3b83b146 Build: Add Windows ARM64 support for library dependencies
* VS2022 is required.
* Only OpenPGL and DPCPP are disabled, other libraries are supported.
* Embree is built with LLVM and VS2019 tools, and for that reason has
  its own cmake file as it is quite different.
* TBB and USD patches should become obsolete once these are upstreamed
  and Blender upgrades to the latest versions.
