This PR adds a bunch of typing for rdflib.graph, mainly as a baseline
for adding typing to rdflib.store which I will do next.

I have resorted to using type aliases for typing all the functions, in
part because it makes it easier to change in the future, however autodoc
type hints do not work particularly well with this which is why I will
switch to https://github.com/tox-dev/sphinx-autodoc-typehints in a
separate patch.

This patch only contains typing changes and does not change runtime
behaviour.

This patch adds more type hints for rdflib.graph, mainly as a baseline
for adding typing to rdflib.store which I will do next.

I have resorted to using type aliases, in part because it makes it
easier to change in the future and to keep everything consistent.

One downside to the type aliases is that autodoc type hints do not
work particularly well with this which is why I will
switch to https://github.com/tox-dev/sphinx-autodoc-typehints in a
separate patch.

This patch primarily adds more type hints for `rdflib.graph`, but also
adds type hints to some related modules in order to work with the new
type hints for `rdflib.graph`.

I'm mainly doing this as a baseline for adding type hints to
`rdflib.store`.

I have created type aliases to make it easier to type everything
cosnsitently and to make type hints easier easier to change in the
future. The type aliases are private however (i.e. `_`-prefixed) and
should be kept as such for now.

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 <RDFLib#1850>.

More or less complete type hints for `rdflib.plugins.sparql.algebra` and
`rdflib.plugins.sparql.operators`.

This does not change runtime behaviour.

Other changes:
- Fixed line endings of `test/test_issues/test_issue1043.py`
  and `test/test_issues/test_issue910.py`.
- Removed a type hint comment that was present in rdflib/plugins/sparql/algebra.py
