[Tizen][Debug] Assert @gpu_process_host_ui_shim.cc(224)

[Tizen][Debug] Assert @gpu_process_host_ui_shim.cc(224)

https://codereview.chromium.org/369003002/ has removed the
handler of GpuHostMsg_UpdateVSyncParameters from GpuProcssHostUIShim.
Our chromium-efl downstream port was the last client of it.

In order to not leave this message unhandled (and hit an assert)
patch adds a filter for it in RenderWidgetHostViewEfl. To to hook
it up, it abuses the existing :RWHVEfl:AcceleratedSurfaceInitialized
callback, which is known to be called when the Gpu process is set up.

Code is based on BrowserCompositorOutputSurfaceProxy::ConnectToGpuProcessHost.
