Delayed annotation evaluation

Most of these look newer than when the original imports referenced in the previous commit were dropped, so these weren't covered by the backout. These were found with: hg files mercurial hgext hgext3rd -I '**.py' -X '**/thirdparty' \ | xargs grep -L 'from __future__ import annotations' All of the `__init__.py` files that finds are empty, so those were ignored and the rest manually edited.

Now that py36 is no longer supported, we can postpone annotation evaluation. This means that the quoting is usually optional (for things imported under the guard of `if typing.TYPE_CHECKING:` to avoid circular imports), and there's less overhead on startup[1]. There may be some missing here. I backed out 6000f5b25c9b (which removed the `from __future__ import ...` that was supporting py2), reverted the changes in `contrib/`, `doc/`, and `tests/`, and then ran: $ hg status -n --change . | \ xargs sed -i -e 's/from __future__ import .*$/from __future__ import annotations/' There were some minor tweaks needed when reviewing (mostly making the spacing around the import consistent, and `mercurial/testing/__init__.py` had a multiline import that wasn't fully rewritten.

Black was not adding them until the next changeset introduced a bunch of `from __future__ import annotations` to most file. Since it make the next changeset hard to read we introduce them in advance.
