evolvestate: rename the file to state.py and class name to cmdstate

The evolvestate.py and the evolvestate class in it were introduced to help `hg
evolve` grow continue and abort options. But the class and it's API can be
easily used to store state information for other state files like we stored the
information for grab state in the previous commit. Let's rename the the file and
class.
