Dan Scales 229b909313 cmd/compile: don't do Resolve on OKEY identifiers during import
For generic functions, we can export untransformed OKEY nodes, and the
key identifier is written as an ONONAME. But in this case, we do not
want to call Resolve() on the identifier, since we may resolve to a
global type (as happens in this issue) or other global symbol with the
same name, if it exists. We just want to keep the key identifier as an
Ident node.

To solve this, I added an extra bool when exporting an ONONAME entry,
which indicates if this entry is for a key or for a global (external)
symbol. When the bool is true (this is for a key), we avoid calling
Resolve().

Fixes #49497
