Update micropython-stdlib

Functional changes:

Typechecking now works correctly for namedtuples.

No changes are needed ,
you may be able to remove some # type: ignore comments if you used them to suppress false-positive typechecking errors.

Details:

This release is focused on micropython-stdlib-stubs and the packages that depend on it.

• Rebuilt micropython-stdlib-stubs based on a recent version of the typeshed stdlib
• Created a script to automate the rebuild, and allow future updates
• Updated micropython-*-stubs to use the new micropython-stdlib-stubs
• Updated micrpython-stubber with new functionality to automate this approach
• additional stub-QA tests have been added to pytest and the CI workflow

The stdlib/collections module needed to be updated with MicroPython specific configuration, as the typecheckers have special handling for namedtuple that only works if it is decalred in stdlib/collections, and not in other modules.
In order to make this work :

• the micropython-stdlib-stubs package now includes a copy of the stdlib/collections stub.
  • this has been updated with micropython specific docstring
  • __all__ has been changed to only export micropython supported types
• the micropython-*-stubs packages:
  • no longer include a copy of the collections.pyi stub
  • include a shim stub for ucollections.pyi that imports * from collections
  • have been updated micropython-stdlib-stubs^=1.1.0.

micropython-*-stubs that have been updated to use the new micropython-stdlib-stubs are:

• v1.19.1.*
• v1.20.0.*
• v1.21.0.*
• prerelease a.k.a. latest
