Add the unified PlatformGraphics module, which looks for either Integrity or VxWorks platform graphics. The PlatformGraphics module creates the interface PlatformGraphics::PlatformGraphics target which links the respective platform graphics target. It's expected that from the platform graphics targets to deliver the consistent subset of definitions, libraries, include directories, compiler and linker flags and also the special <platform>_REQUIRED_<LIBRARIES|INCLUDES|DEFINITIONS> variables. The <platform>_REQUIRED_<LIBRARIES|INCLUDES|DEFINITIONS> variables are consumed by the PlatformGraphics::PlatformGraphics and stored in the respective _qt_internal_platform_graphics_required_<type> property, to access the value without scope limitations. The property then is checked by the EGL and GLESv2 modules(this can be done elsewhere too) and is appended to the CMAKE_REQUIRED_<type> variable before running the respective compiler checks.
