typing: add some type annotations to mercurial/phases.py
Some of these were helpful in typing other modules, and then I typed the
easy-ish ones. Black forces the long `Phasedefaults` definition to be wrapped,
which pytype seems OK with (as shown with `reveal_type()`), but it does seem to
confuse PyCharm a bit.
