[NFC][Py Reformat] Reformat python files in lldb

[JDevlieghere]

Summary

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with black.

If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Thanks for doing this! Going to assume you ran the tests and it worked :)

Yup, no regressions. I'll keep an eye on the bots to make sure that holds true for other configurations too.

Can you add this commit hash to the .git-blame-ignore-revs file so it doesn't show up in the git history

Yeah that should be done. But has to be done after arc land anyway.

Yup, but as Tobias pointed it needs to be committed first in order to get the hash.
