compositor: Move WebRender-ish messages and types to webrender_traits (#32315)

Browse source 
* Move WebRender related types to `webrender_traits`

This refactor moves several WebRender related types
from `compositing_traits`, `script_traits` and `net_traits`
crates to the `webrender_traits` crate.

This change also moves the `Image` type and associated
function out of `net_traits` and into the `pixels` crate.

* Move `script_traits::WebrenderIpcSender` to `webrender_traits::WebRenderScriptApi`
