[Site-isolation] Add display-only NativeImages recorded across processes
https://bugs.webkit.org/show_bug.cgi?id=326296
<rdar://problem/189145600>
Reviewed by Kimmo Kinnunen.
Add Chrome::createDisplayOnlyImage(), which records a rendering in the GPU
process so that frames hosted in other processes can contribute. It returns a
promise that resolves, once every frame has recorded, to a NativeImage that the
web process can display but not read.
The GPU process draws into an IOSurface that it hands to the UI process, which
holds the image. The web process gets a DisplayOnlyImageProxy, a NativeImage
with
no platform image, which releases the image when destroyed.
GraphicsLayerCARemote
sends its identifier as layer contents.
No new tests: nothing calls this yet. A view transitions caller is next.
