Bug 1924152 - Support rendering without presenting. r=gw

Browse Source 
The goal for this initial implementation is to be able to render picture snapshots without presenting the frame, but it could be extended to supporting some picture cache slices without presenting (for example if we know that the picture is not affected by scrolling or animated properties and want to start rendering it early).
