This CL removes Type and TypeSchema type variables from the abstract
classes with shared code between the CFE and the analyzer. Extension
types SharedTypeView and SharedTypeSchemaView are declared to replace
the type variables.
The update propagates the discipline of distinguishing between types
and type schemas into the clients of the shared code. Now the code in
the CFE and the Analyzer that uses the shared code needs to statically
specify the interpretation of their type objects as either types or
type schemas.
Another benefit of the update is SharedTypeView and
SharedTypeSchemaView being less opaque than the Type and TypeSchema
type variables, which removes the necessity for some code duplication
in abstract methods for types and type schemas.
Finally, the update enables some further changes in the shared code
between the Analyzer and the CFE.
