SDL_render: Call InvalidateCachedState to initialise some of driverdata values (eg '*_dirty' to 1).

At the earliest place, immediatly after driverdata is set.
(Doing it in SDL_render.c, after creation, would be too late, because there're renderers that already use/change those values in the CreateRender() function).
