repo: try to support opening uninitialized/broken repositories (#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 #10719. #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.

-## Summary / Background
-What do you want to achieve, why? business context
-...
-
-## Scope
-
-What will be impacted and what won't be?
-What needs implementation and what is invariant?
-e.g.
-- user should be able to run workflow X from UI
-- enable workflow Y, Z from CLI
-
-## Assumptions
-Product / UX assumptions as well as technical assumptions / limitations
-e.g.
-* Support only Python Runtime
-* Focus on DVC experiments only
-* Deployment environments don't change often and can be picked up from shared configuration
-
-## Open Questions
-e.g.
-- How should access control work for shared artifacts (workflow X)
-- Python runtime assumption - is it really valid? in light of <...>
-
-## Blockers / Dependencies
-List issues or other conditions / blockers
-
-## General Approach
-Invocation example:
-```shell
-$ mapper-run task.tar.gz --ray-cluster <ip>:<port>
-```
-
-## Steps
-
-### Must have (p1)
-- [ ] subissue2
-- [ ] step 2
- - info
- - info
-
-### Optional / followup (p2)
-- [ ] ⌛ step 3 wip
-- [ ] step 4
-
-## Timelines
-
-Put your estimations here. Update once certainty changes
-- end of week (Feb 3) for prototype with workflows X, Y
-- Feb 15 - MVP in production
-- Low priority followups can be done later
