mypy 2.0 big change list

[hauntsaninja]

• Local partial types
• PEP 688 change bytearray memoryview promotion by default
• Remove logic for legacy bundled stubs
• Interpret type as type[Any]?
• SQLite cache
• Delete the Python 2 extra from setup.py

This is a reminder list for relatively easy changes we may want to do in a major version.

For general not-so-easy changes we want to do, see https://github.com/python/mypy/issues/16472 (major/minor isn't the most meaningful for a lot of the most important changes we want to do, e.g. --new-type-inference was in 1.7)
