Subject: [PATCH 1/2] ci: configure tox to pass environment variables for
 PyTorch

tox's isolated environment blocks `USERNAME` by default, causing
PyTorch's `torch._inductor` to fail during import when it calls
`getpass.getuser()` for cache directory setup.

Pass through username and temp directory variables, and set
`TORCHINDUCTOR_CACHE_DIR` explicitly to avoid the getpass call.

Fixes Windows Python 3.10/3.11 test failures.
