torchao not installed by default for ExecuTorch 0.6 RC

[mergennachin]

🐛 Describe the bug

After I install

pip install --extra-index-url https://download.pytorch.org/whl/test/cpu executorch==0.6.0

The following commmand doesn't work:

import torchao

Let's either

• pin to particular version of ao in pyproject.toml directly similar to https://github.com/pytorch/executorch/pull/8038/files
• Make pip wheel build ao from third-party/ao submodule

If we go with the first route, one thing to make sure is that third-party/ao submodule hash is the same as pinned torchao release
