Forward args to _get_remote_config() and honour core/no_scm if present (#10719)

* Forward args to _get_remote_config and honour core/no_scm if present

* Pass full config, except cache, to Repo()

* Avoid modifying original kwargs contents

* Simplify if config

* Add test

* Relax error matching.. .. Avoid windows vs unix paths

* Update dvc/repo/open_repo.py
