checkout: make delayed checkout respect --quiet and --no-progress

The 'Filtering contents...' progress report from delayed checkout is
displayed even when checkout and clone are invoked with --quiet or
--no-progress. Furthermore, it is displayed unconditionally, without
first checking whether stdout is a tty. Let's fix these issues and also
add some regression tests for the two code paths that currently use
delayed checkout: unpack_trees.c:check_updates() and
builtin/checkout.c:checkout_worktree().
