Add markup support to generic wxStaticText implementation.

wxMarkupText allows to easily support markup in the controls that we draw
ourselves so use it in wxGenericStaticText to have a possibility to use
markup on all platforms, even those where there is no native markup support in
wxStaticText itself.
