[PATCH v6 4/6] worktree: be clearer when "add" dwim-ery kicks in

Currently there is no indication in the "git worktree add" output that a new branch was created. This would be especially useful information in the case where the dwim of "git worktree add <path>" kicks in, as the user didn't explicitly ask for a new branch, but we create one for them.

Print some additional output showing that a branch was created and the branch name to help the user.

This will also be useful in a subsequent commit, which introduces a new kind of dwim-ery of checking out the branch if it exists instead of refusing to create a new worktree in that case, and where it's nice to tell the user which kind of dwim-ery kicked in.
