[PATCHv3 5/6] submodule-config: remove submodule_from_cache

[Stefan Beller]

This continues the story of bf12fcdf5e (submodule-config: store
the_submodule_cache in the_repository, 2017-06-22).

The previous patch taught submodule_from_path to take a repository into
account, such that submodule_from_{path, cache} are the same now.
Remove submodule_from_cache, migrating all its callers to
submodule_from_path.
