Advance release version to 2.12.1 and drop Windows libtorch debug builds (#8194)

## Summary

Two changes to `tools/scripts/generate_binary_build_matrix.py`:

1. **Advance release version to 2.12.1** - bump
`CURRENT_CANDIDATE_VERSION` and `CURRENT_STABLE_VERSION` from `2.12.0`
to `2.12.1`, and regenerate the wheel build-matrix test assets (only the
embedded `stable_version` changes).
2. **Remove Windows libtorch debug builds** - drop `DEBUG` from the
Windows libtorch `abi_versions`, so only release builds are generated.
This removes the debug binaries from both the nightly and release
channels, mirroring pytorch/pytorch no longer building/publishing
Windows libtorch debug binaries.

## Effect

Windows libtorch matrix goes from 8 entries (4 release + 4 debug) to 4
(release only):

```
BEFORE: total 8  Counter({'release': 4, 'debug': 4})
AFTER:  total 4  Counter({'release': 4})
```

## Testing

`python3 -m unittest discover -s tools/tests -p
test_generate_binary_build_matrix.py` - all 7 wheel-matrix tests pass
with the regenerated assets. libtorch matrices are not covered by the
asset tests, so the debug removal needs no asset changes.
