Matthew Dempsky f0b1563535 cmd/compile/internal/types: remove unneeded functionality
This CL removes a handful of features that were only needed for the
pre-unified frontends.

In particular, Type.Pkg was a hack for iexport so that
go/types.Var.Pkg could be precisely populated for struct fields and
signature parameters by gcimporter, but it's no longer necessary with
the unified export data format because we now write export data
directly from types2-supplied type descriptors.

Several other features (e.g., OrigType, implicit interfaces, type
parameters on signatures) are no longer relevant to the unified
frontend, because it only uses types1 to represent instantiated
generic types.

Updates #57410.
