cmd/compile: add required CONVIFACE nodes when translating OFUNCINST node
In CL 349614. we removed the early transformation code that
was needed to create the implicit CONVIFACE nodes.
Because the transformCall function is not called when translating OFUNCINST.
So we add in needed CONVIFACE nodes via typecheckaste().
Fixes #48598
