Enable window size caching on Symbian NGA variants.
Enabling this flag saves us the round-trip to WSERV whenever RWindow::Size() is called because the size is cached on the client side. This can improve performance because functions like eglSwapBuffers() call Size() to see if the window size has changed and without the cache this introduces an extra IPC call for every frame.
