egl: Introduce platform displays internally.

This commit introduces type-safe platform displays internally.  A
platform display consists of a generic pointer and an enum that
specifies the platform.

An EGLDisplay is created from a platform display.  Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform().  Platform windows and pixmaps may also be
introduced if needed.
