[ty] Further improve details around which expressions should be deferred in stub files (#21456) 
## Summary

- Always restore the previous `deferred_state` after parsing a type
expression: we don't want that state leaking out into other contexts
where we shouldn't be deferring expression inference
- Always defer the right-hand-side of a PEP-613 type alias in a stub
file, allowing for forward references on the right-hand side of `T:
TypeAlias = X | Y` in a stub file

## Test Plan

I added a regression test for a regression that the first version of
this PR introduced (we need to make sure the r.h.s. of a PEP-613
`TypeAlias`es is always deferred in a stub file)

Markdown files within the mdtest/ subdirectory are tests of type inference and type checking; executed by the tests/mdtest.rs integration test.

See crates/ty_test/README.md for documentation of this test format.
