typing: hide the interface version of `dirstate` during type checking...

typing: hide the interface version of `dirstate` during type checking As noted in the previous commit, the `dirstate` type is still inferred as `Any` by pytype, including where it is used as a base class for the largefiles dirstate. That effectively disables most type checking. The problems fixed two commits ago were flagged by this change. I'm not at all clear what the benefit of the original type is, but that was what was used at runtime, so I don't want to change the largefiles base class to the raw class. Having both a lowercase and camelcase name for the same thing isn't great, but given that this trivially finds problems without worrying about which symbol clients may be using, and the non-raw type is useless to pytype anyway, I'm not going to worry about it.
