go/types, types2: make sure info recording is executed in test runs

Issue #61486 causes a compiler crash but is not detected when running
stand-alone type-checker tests because no types are recorded.

Set up Config.Info map with all maps when when running local tests
so that type/object recording code is executed during local tests.

For #61486.
