switch from typing.Callable to collections.abc.Callable

[jameslamb]

Description

Follow-up to #16637.

Once this project's minimum support Python version was bumped up to Python 3.10, ruff started raising this error from pyupgrade:

Import from `collections.abc` instead: `Callable`

• ruff docs: https://docs.astral.sh/ruff/rules/deprecated-import/
• typing docs saying that typing.Callable is deprecated starting in Python 3.9 https://docs.python.org/3/library/typing.html#typing.Callable
• context: Drop Python 3.9 support #16637 (comment)

This proposes accepting that suggestion, so that cudf won't be broken whenever Callable is removed from the typing module.

Notes for Reviewers

Some of the imports added in this PR are put into if TYPE_CHECKING blocks because of this other error from ruff:

TCH003 Move standard library import `collections.abc.Callable` into a type-checking block

These changes look good to me, thanks James!

I'm happy to have imports in TYPE_CHECKING blocks (even if not avoiding circular imports), FWIW.

Thanks for the reviews, and for the nudge to change this across cudf @wence-
