Golang cmd/compile: can't use aliased type as underlying type in type parameter [1.23 backport]

@cuonglm requested issue #68935 to be considered for backport to the next 1.23 minor release.

@gopherbot please backport this issue to go1.23 release.

This is a bug in compiler type checker without any workaround.
