sem: Use UniqueAllocator for types

Add a Hash() and Equals() methods to sem::Type.

Have sem::Manager (which should be called sem::TypeManager) derive from
utils::UniqueAllocator. This now uses the Hash() and Equals() for uniquely
constructing semantic types instead of building strings and comparing those.
