typing: add type hints to `mercurial.shelve`

Pytype wasn't flagging anything here yet, but PyCharm was really unhappy about
the usage of `state` objects being passed to various methods that accessed attrs
on it, without any obvious attrs on the class because there's no contructor.
Filling that out made PyCharm happy, and a few other things needed to be filled
in to make that easier, so I made a pass over the whole file and filled in the
trivial hints.  The other repo, ui, context, matcher, and pats items can be
filled in after the context and match modules are typed.

def run():
    from . import demandimport

    with demandimport.tracing.log('hg script'):
        demandimport.enable()
        from . import dispatch

        dispatch.run()


if __name__ == '__main__':
    run()
