submodule: add absorb-git-dir function
When a submodule has its git dir inside the working dir, the submodule support for checkout that we plan to add in a later patch will fail. Add functionality to migrate the git directory to be absorbed into the superprojects git directory. The newly added code in this patch is structured such that other areas of Git can also make use of it. The code in the submodule--helper is a mere wrapper and option parser for the function `absorb_git_dir_into_superproject`, that takes care of embedding the submodules git directory into the superprojects git dir. That function makes use of the more abstract function for this use case `relocate_gitdir`, which can be used by e.g. the worktree code eventually to move around a git directory.

DESCRIPTION

If `--recursive` is specified, this command will recurse into the
registered submodules, and sync any nested submodules within.
+absorbgitdirs::
+ If a git directory of a submodule is inside the submodule,
+ move the git directory of the submodule into its superprojects
+ `$GIT_DIR/modules` path and then connect the git directory and
+ its working directory by setting the `core.worktree` and adding
+ a .git file pointing to the git directory embedded in the
+ superprojects git directory.
++
+A repository that was cloned independently and later added as a submodule or
+old setups have the submodules git directory inside the submodule instead of
+embedded into the superprojects git directory.
++
+This command is recursive by default.
