t7002: add tests for moving from in-cone to out-of-cone

Browse source 
Add corresponding tests to test that user can move an in-cone <source>
to out-of-cone <destination> when --sparse is supplied.

Such <source> can be either clean or dirty, and moving it results in
different behaviors:

A clean move should move <source> to <destination> in the index (do
*not* create <destination> in the worktree), then delete <source> from
the worktree.

A dirty move should move the <source> to the <destination>, both in the
working tree and the index, but should *not* remove the resulted path
from the working tree and should *not* turn on its CE_SKIP_WORKTREE bit.

Also make sure that if <destination> exists in the index (existing
check for if <destination> is in the worktree is not enough in
in-to-out moves), warn user against the overwrite. And Git should force
the overwrite when supplied with -f or --force.
