cmd/compile: fix naming of types inside instantiations Issues 47713 and 47877 were both due to problems with the names used for instantiated functions/methods, which must be in sync with the names used by types2. - Switched to using NameString() for writing out type arguments in instantiation names. This ensures that we are always adding the package to type names even for the local package. Previously, we were explicitly adding the package name for local packages, but that doesn't handle the case when the local type is embedded inside a pointer or slice type. By switching to NameString(), we fix #47713. - types1 and types2 write out 'interface {' differently (vs. 'interface{') and we were already handling that. But we needed to add similar code to handle 'struct {' vs 'struct{'. This fixes issue #47877. While fixing these bugs, I also moved some duplicated code (which include some of the changes above) into a common function addTargs(). I also moved InstType() name to subr.go, and renamed: MakeInstName -> MakeFuncInstSym and MakeDictName -> MakeDictSym. Also removed a couple of ".inst..inst." prefix checks which are irrelvant now, since we don't add ".inst." anymore to function instantiations.
