go/types, types2: distinguish between substring and regexp error patterns
Use ERROR for substrings, and ERRORx for regexp error patterns.
Correctly unquote patterns for ERROR and ERRORx.
Adjust all tests in internal/types/testdata and locally as needed.
The changes to internal/types/testdata were made through
repeated applications of regexpr find/replace commands
and manual cleanups.
Fixes #51006.
