`inspect.getfullargspec` still needs `from __future__ import annotations`

Bug report

Bug description:

This issue arose from micheles/decorator#177. In essence, inspect.getfullargspec still needs from __future__ import annotations. Example:

from inspect import getfullargspec
from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from collections.abc import Sequence

def foo(ints: Sequence[int]) -> None:
    pass

print(getfullargspec(foo))
# TypeError: unsupported callable
