Matthew Dempsky 1a2435c95f go/types, cmd/compile: fix composite literal structural typing
For a composite literal expression like []T{{f: 1}}, we allow T to be
a pointer to struct type, so it's consistent to allow T to also be a
type parameter whose structural type is a pointer to struct type.

Fixes #50833.
