submodule: factor out a config_set_in_gitmodules_file_gently function

Introduce a new config_set_in_gitmodules_file_gently() function to write
config values to the .gitmodules file.

This is in preparation for a future change which will use the function
to write to the .gitmodules file in a more controlled way instead of
using "git config -f .gitmodules".

The purpose of the change is mainly to centralize the code that writes
to the .gitmodules file to avoid some duplication.

The naming follows git_config_set_in_file_gently() but the git_ prefix
is removed to communicate that this is not a generic git-config API.
