Implement QPlatformOpenGLContext using EGL. To use it in platform
plugins a subclass must be created since
eglSurfaceForPlatformSurface() has to be reimplemented. This
function is used for mapping platform surfaces (windows) to EGL
surfaces and is necessary since different platform plugins may
have different ways of handling native windows (for example, a
plugin may choose not to back every platform window by a real EGL
surface). Other than that, no further customization is necessary.
