repo: try to support opening uninitialized/broken repositories (treev…

…erse#10736)

This `_get_remote_config()` should use `uninitialized=True` so that it supports
more broader kinds of broken/partially-initialized repositories, including some that have
`.dvc` directory missing, or `.git` directory missing.

This partially reverts treeverse#10719. treeverse#10608 is also fixed, and no longer requires `core.no_scm` to be passed.
This was already supported by `dvc.api.get_url` as it uses `uninitialized=True`, but this was not respected
in `_get_remote_config()` where it would fail before.

That said, this whole `open_repo`/`_get_remote_config` is terribly broken. For one, it is opening
a local repository, and forcing it's remote config to a repository opened with `Repo(rev=...)`,
where the config may be different.

3.13 support for Windows (treeverse#10667)

python/cpython#113829 changed `os.path.isabs` on Windows to not consider a path starting a single backslash to be an absolute path.

We do a lot of naive `posixpath` to `ntpath` conversions, and it broke DVC in multiple places. DVC is likely broken in many other places, and these bugs are difficult to identify.

In this commit, I have tried to fix in the places where the tests failed. And mostly by trying to imitate pre-3.13 behaviour.
Some of the changes may not be correct but keeps the old behaviour in place.

Also re-enabled the CI for all Python versions supported for Windows.

Fix treeverse#10638 : makes remove return correct list when used with…

… both `--queue` and `-A` (treeverse#10641)

* fixed a bug where using both `--queue` and `-A` would yield a "removed" list without the queued experiments

* added a test to validate the fix

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* clearer name for test
