cmd/compile, types2: better error message for invalid type assertion This CL addresses the 2nd part of the issue below. - For types2, now use the same error messages as the compiler in this case. - Make the mechanism for reporting clarifying error messages handle the case where we don't have additional position information. - Provide context information (type assertion vs type switch). Fixes #49005.
