    This PR adds `StateInternalsFactory` which is a map from a key to `StateInternals`. Since `GroupAlsoByWindow` is now truly an implementation detail of `GroupByKey`(`ViaGroupByKeyOnly`), we can just provide it the state access that it needs.
    
    This is a step both in the progress of moving runner implementation details out of the SDK and also in providing a better user-facing state API.

    Introduce StateInternalsFactory
    
    This class vends a StateInternals for a particular key.
    Various DoFns that access StateInternals via ProcessContext
    will be ported to instead accept a StateInternalsFactory.
    
    The StateInternalsFatory must be provided by the runner
    to enable provisioning of the appropriate run-time
    StateInternals.
