test: modernize idiom in wasmguest tests (slices.Contains, any, new(v))

- driver_test.go: use slices.Contains instead of a hand-rolled loop
- sqlcgen_test.go: interface{} -> any in the generated-style DBTX shim
- caps_roundtrip_test.go: new(idParent.String()) instead of proto.String
  for the pointer literal
