feat: Add type hints to rdflib.graph (#2080)

More or less complete type hints for the rdflib.graph module.

Other changes:
- Improved/simplified type hints in `rdflib.store` and store plugins.
- Add type ignores for various type errors that occur with the type
  hints.

This is split-off from <https://github.com/RDFLib/rdflib/pull/1850>.

This PR does not change runtime behaviour.
