Enable git_submodules tests and merge git_repository and starlark_git_repository (bazelbuild#17247)

- Added necessary flags to allow clone submodule from local repository.
- We only have the starlark version of git repository rule and most test cases in two integration tests are duplicated.

Fixes bazelbuild#17040
