Convert typing declarations to use TypeAlias

See original GitHub issue

See discussion here: https://github.com/pandas-dev/pandas-stubs/pull/341#issuecomment-1262928643

Should we change _typing.pyi to make all these types that we create be declared with TypeAlias (imported from typing_extensions) ?

@twoertwein - your opinion?

Fun fact: typeshed pretends that typing_extensions is part of the standard library, meaning that all type checkers also believe that typing_extensions is part of the standard library. This means that (since this is a stubs-only project, and will never be executed at runtime) you should be able to use types from typing_extensions (and also _typeshed, which we treat similarly) without adding a dependency on typing_extensions 😃

Could also start using _typeshed.Self in the stubs (Y019) @Dr-Irv
