direct2d: Work around ClearType rendering bug in translucent mode

This switches the font rendering to use gray scale antialiasing when in
translucent rendering mode. It does so by adding a flags argument to the
paint engine, allowing for future expansion in communicating render hints
from the device to the engine.

Task-number: QTBUG-41002
