Jeff Gilbert a97c615de2 Bug 1632249 - Support compositing out-of-process WebGL. r=handyman,lsalzman,nical,geckoview-reviewers,agi,imanol
* Majorly simplity CanvasRenderer
* Replace GLScreenBuffer with trivial GLSwapChain
* Use descriptor structs so that future SharedSurface changes aren't so painful
  to propagate
* Mortgage/strip out more OffscreenCanvas code for now
