[Release 0.6] bump torchao pins (#9964)

This PR bumps the torchao pins for the ExecuTorch 0.6 release branch to
the torchao 0.10.0 release:

1. The pin in third-party/ao is bumped to branch "release/0.10.0".
2. We add "torchao==0.10.0" to the pyproject.toml.

This is intended to address
#9940 and follows the
corresponding bin bump in third-party/ao on main
(https://github.com/pytorch/executorch/pull/9947/files).
