Clean up docstrings in python interfaces to be strictly typed/formatted

* Also added a script that can run as part of CI to verify that the docstring
  matches, by generating a regex from the docstring documented parameter types
  and return type and making sure we find a match within the C headers. This
  ensures all parameters are documented with the right types, no extra
  parameters are documented, and the return type is correct.
* The script also checks proper scoping so that if qrenderdoc docstrings
  mention a renderdoc type, they need to scope it properly.
