cmd/go: produce a better error for generic test functions

Test functions with type parameters cannot be invoked without type
arguments, so cmd/go would previously fail with a type-checking error in
the test harness.

Avoid this by producing an error explaining that test functions cannot
have type parameters.

Fixes #48953
