Dan Scales 80783558b0 cmd/compile: make sure imported instantiated types have their methods created 
We should be putting a newly instantiated imported type in
Instantiate/doInst onto the instTypeList, so its methods/dictionaries
are instantiated. To do this, we needed a more general way to add a
type to instTypeList, so add NeedInstType(), analogous to
NeedRuntimeType(). This has the extra advantage that now all types
created by the type substituter are added to instTypeList without any
extra code, which was easy to forget. doInst() now correctly calls
NeedInstType().

This is a bit aggressive, since a fully instantiated type in a generic
function/method may never be used, if the generic method is never
instantiated in the local package. But it should be fairly uncommon for
a generic method to mention a fully instantiated type (but it does
happen in this bug).

Fixes both cases mentioned in the bug.

Fixed #48185
