config: move config_from_gitmodules to submodule-config.c

The .gitmodules file is not meant as a place to store arbitrary
configuration to distribute with the repository.

Move config_from_gitmodules() out of config.c and into
submodule-config.c to make it even clearer that it is not a mechanism to
retrieve arbitrary configuration from the .gitmodules file.
