refactor how font, fg. and bg. are applied in widgets/controls

- Move vcl::RenderContext to outdev.
- Change some methods on vcl::Window to accept RenderContext
as parameter.
- Add ApplySettings to vcl::Window - This method is called before
painting. Refactor existing classes that use InitSettings to
have ApplySettings or mark the classes to be refactored later.
- Add RenderSettings for adding defered settings to rendering.
This is similar to ApplySettings but for more ad-hoc calls.
