builtin/submodule--helper: add gitdir command
This exposes the gitdir name computed by submodule_name_to_gitdir() internally, to make it easier for users and tests to interact with it. Next commit will add a gitdir configuration, so this helper can also be used to easily query that config or validate any gitdir path the user sets (submodule_name_to_git_dir now runs the validation logic, since our previous commit).
