Remove GpuHostMsg_UpdateVSyncParameters handler from GpuProcssHostUIShim
After delegated frame is used, this message is not handled anymore
by GpuProcessHostUIShim.
On Aura, this message is handled by BrowserCompositorOutputSurfaceProxy.
On Mac, vsync params updating is triggered not by gpu process
but by browser process itself with DisplayLinkMac.
On Android, browser process uses android system's vsync signal.
