Fixed incompatible use of constrained TypeVar in tempfile. (#5043)

Browse Source 
The TypeVar `_T` was being used as a type argument for `PathLike`, but `PathLike` requires that its type argument be constrained to `str` or `bytes`, and `_T` didn't provide any such constraint. The easy workaround is to use the TypeVar `AnyStr` instead.
