[dev.typeparams] cmd/compile: add derived-type dictionaries to unified IR

Browse source 
This CL updates the unified IR export data serialization to explicitly
and separately record the derived types used by a declaration. The
readers currently just use this data to construct types/IR the same as
before, but eventually we can use it for emitting GC-shape
dictionaries.
