Allow nesting of Annotated with TypedDict special forms inside TypedDicts

[brianschubert]

This is allowed per the typing spec.

Updates the TypeAnalyzer to remember whether TypedDict special forms are allowed when visiting Annotated types.

With this, mypy passes the typeddicts_readonly and typeddicts_required conformance tests:
