Allow additional text to folllow formatter pragma comments

format doctests in docstrings (#8811 )
## Summary This PR adds opt-in support for formatting doctests in docstrings. This reflects initial support and it is intended to add support for Markdown and reStructuredText Python code blocks in the future. But I believe this PR lays the groundwork, and future additions for Markdown and reST should be less costly to add. It's strongly recommended to review this PR commit-by-commit. The last few commits in particular implement the bulk of the work here and represent the denser portions. Some things worth mentioning: * The formatter is itself not perfect, and it is possible for it to produce invalid Python code. Because of this, reformatted code snippets are checked for Python validity. If they aren't valid, then we (unfortunately silently) bail on formatting that code snippet. * There are a couple places where it would be nice to at least warn the user that doctest formatting failed, but it wasn't clear to me what the best way to do that is. * I haven't yet run this in anger on a real world code base. I think that should happen before merging. Closes #7146 ## Test Plan * [x] Pass the local test suite. * [x] Scrutinize ecosystem changes. * [x] Run this formatter on extant code and scrutinize the results. (e.g., CPython, numpy.)
