Centralize Python linter/formatter requirements (#8854)

These are currently duplicated all over the codebase, often with
mismatched constraints. Put them all in one requirements file instead.

Fix a few minor issues while I'm at it:

* Constrain black to the current major version to avoid New Year
surprises (black can change styles between major versions). Constrain
isort too, just in case.

* Remove usages of `egrep`, which is deprecated (and unnecessary here).
