Clean up mojom::Renderer usage in RPH

Clean up mojom::Renderer usage in RPH

This gets rid of the ugly UserData + static accessor pattern
which was used to expose a private mojom interface on RPH.

Instead the mojom interface is forward-declared and a public
accessor is added to RPH despite being unusable by content
embedders.
