VideoCommon: Call Renderer::SurfaceChanged on render parent resize

This is needed because for some reason the WSI for NV Vulkan drivers
doesn't return VK_ERROR_OUT_OF_DATE_KHR, so there is no other way to know
that a resize has occured apart from polling, which is a poor solution for
X11 (since it is blocking).
