directfb: Introduce EGL integration for DirectFB

Introduce a new platform called 'directfbegl' that allows platform
integration with EGL. Change the QDirectFbIntegration to make it more
easy to hook up in the creation process, introduce an EGL integration
with custom screen, window and EGL Platform Context.
Vendors might need to add custom code to initialize EGL to be used with
DirectFB, this can be done in QDirectFbScreenEGL::platformInit.
