Fix OpenUSD binary download and dependency issues in Linux CI

- Fix ARM64 binary pattern: change aarch64 to arm64 to match actual release filename
- Add libtbb12 installation for x86_64 build to resolve missing libtbb.so.12 error

These changes fix the failures in workflow run #20866500999 where:
1. ARM64 build failed with "no assets match the file pattern"
2. x86_64 build failed with "error while loading shared libraries: libtbb.so.12"
