Remove ViewHostMsg_DidFirstPaintAfterLoad

ViewHostMsg_DidFirstPaintAfterLoad is currently stored inside
ViewHostMsg_SwapCompositorFrame, but once ViewHostMsg_SwapCompositorFrame
is mojoified, we don't want to have IPC messages sent using mojo calls.
Fortunately ViewHostMsg_DidFirstPaintAfterLoad can go away after the
introduction of content_source_id in CompositorFrameMetadata a few
weeks ago.

Send FrameSwapMessageQueue's messages with a separate IPC

We can't put messages inside ViewHostMsg_SwapCompositorFrame once it's
mojoified, so those messages need to be sent separately. In order
to achieve this, I added an integer token to CompositorFrameMetadata
and send the same token with the messages to the browser. The browser
uses the token to match frames and messages and once both the frame and
its messages arrive, the messages are processed.

Deserialize frame_token in CompositorFrameMetadata's struct traits

In my last CL I added the serialization code but not deserialization.

This is FIXED I believe! Thanks Saman!
