vcl: move OutputDevice::SetDigitLanguage() to text.cxx

Ultimately I hope to reduce outdevstate.cxx to only have push(), pop()
and clearstack(), then rename outdevstate.cxx to stack.cxx. Eventually,
the plan is to separate metafile processing from rendering.

Add unit test for SetDigitLanguage() and GetDigitLanguage().
