  Revert "Vulkan: Forward RenderBuffer/Surface dirty messages."
  
  This reverts commit 3fb33ade6ec8f286797bff5645304df580b1a963.
  
  Reason for revert: Causing WebGL test failures on GLES/ANGLE/Android.
  
  Bug: chromium:1072739
  
  Original change's description:
  > Vulkan: Forward RenderBuffer/Surface dirty messages.
  > 
  > Previously we were only forwarding Texture staging changes to the
  > Framebuffer for re-sync. We could miss out on clears that were staged
  > in Surfaces and Renderbuffer attachments. Complete the chain by making
  > the SurfaceVk and RenderbufferVk forward notifications from the
  > VkImage.
