Commit Message:
TTS: Enable in Mingw-w64 builds

TTS libraries can now be used in default Mingw-w64 environments.

- Removes reference to sapiddk.h which isn't used and isn't in Mingw-w64
- Defines guids whose symbols are missing from Mingw-w64
- Restores TTS detection to configure script

    backends/text-to-speech/windows/windows-text-to-speech.cpp
    configure
