Rob Findley 63daa774b5 go/types: guard against checking instantiation when generics is disabled
When type checking t[_], where t is a type name, it was possible to leak
an error message related to generics. Fix this by guarding on
typeparams.Enabled.

In order to test this fix, we need to be able to run the new go/types
test only if type parameters are disabled. Introduce the .go1 test data
suffix (similar to .go2) to control this behavior.

Originally found via fuzzing, though the test case was manually
simplified.

Updates #46404
