[red-knot] Add control flow support for match statement (#13241) 
## Summary

This PR adds support for control flow for match statement.

It also adds the necessary infrastructure required for narrowing
constraints in case blocks and implements the logic for
`PatternMatchSingleton` which is either `None` / `True` / `False`. Even
after this the inferred type doesn't get simplified completely, there's
a TODO for that in the test code.

## Test Plan

Add test cases for control flow for (a) when there's a wildcard pattern
and (b) when there isn't. There's also a test case to verify the
narrowing logic.

Vendored types for the stdlib

This crate vendors typeshed's stubs for the standard library. The vendored stubs can be found in crates/red_knot_python_semantic/vendor/typeshed. The file crates/red_knot_python_semantic/vendor/typeshed/source_commit.txt tells you the typeshed commit that our vendored stdlib stubs currently correspond to.

The typeshed stubs are updated every two weeks via an automated PR using the sync_typeshed.yaml workflow in the .github/workflows directory. This workflow can also be triggered at any time via workflow dispatch.
