Add enums and remove python implementation of transfer meshtags to submesh

[jorgensd]

Various Python 3.10 features:

• typing.Optional is now | None.
• Use match-case: https://www.geeksforgeeks.org/python/python-match-case-statement/
• Introduce enums for string based inputs. Should be converted to StrEnum once Python 3.11 is minimum Python.
• Correct typo in Nitsche name.
• typing.List -> list

That looks very neat @jorgensd

It seems the tests are failing though
