windows string macros: Handle _T, _TEXT and TEXT internally, add tests (#1163) 

Remove TEXT() macro from windows.cfg and handle it internally where it
can be correctly simplified (Ansi vs. Unicode).
Also add handling of _TEXT() macro which is just a synonym for _T().
Add tests to verify correct function and macro simplification.
