Originally, "git mv" a sparse file from out-of-cone to in-cone does not update the moved file's sparsity (remove its SKIP_WORKTREE bit). And the corresponding cache entry is, unexpectedly, not checked out in the working tree. Update the behavior so that: 1. Moving from out-of-cone to in-cone removes the SKIP_WORKTREE bit from corresponding cache entry. 2. The moved cache entry is checked out in the working tree to reflect the updated sparsity.
