When submodule is a linked worktree, "git diff --submodule" and other
calls which directly access the submodule's object database do not correctly
calculate its path. Fix it by changing the git_pathdup_submodule() behavior,
to use either common or per-worktree directory.
Do it similarly as for parent repository, but ignore the GIT_COMMON_DIR
environment variable, because it would mean common directory for the parent
repository and does not make sense for submodule.
Also add test for functionality which uses this call.

With the introduction of "git worktree add", "git checkout --to" is
slated for removal. Therefore, retrofit linked worktree creation tests
to use "git worktree add" instead.
(The test to check exclusivity of "checkout --to" and "checkout <paths>"
is dropped altogether since it becomes meaningless with retirement of
"checkout --to".)

Each working directory of main repository has its own working directory
of submodule, and in most cases they should be checked out to different
revisions. So they should be separated.
It looks logical to make submodule instances in different working
directories to reuse the submodule directory in the common dir of
the main repository, and probably this is how "checkout --to" should
initialize them called on the main repository, but they also should work
fine being completely separated clones.
Testfile t7410-submodule-checkout-to.sh demostrates the behavior.
