  Vulkan: Implement multi-threaded GL.
  
  The main component of this change is to make vk::BufferHelper,
  vk::ImageHelper and vk::SyncHelper use a common path. We introduce a
  new "vk::SharedGarbage" helper class that stores small lists of garbage
  from individual objects like an ImageHelper or BufferHelper. The
  SharedGarbage is stored in the RendererVk with the ResourceUse of the
  helper object. The ResourceUse tells RendererVk when it is safe to
  destroy the GarbageObjects.
  
  New "onGraphAccess" commands are added in a few places to enable the
  common garbage collection path. A couple Context-only resources like
  default attributes now are referenced where they were not before.
  
  Also reorganizes some functions so we can add a few helpful ASSERTs
  to our graph dependencies. Added "updateCurrentAccessNodes" for this.
  
  Also adds a "RendererScoped" helper to replace many uses of
  "ContextScoped".
  
  The multithreading EGL tests mostly pass but have some remaining
  flakiness so cannot yet be enabled.
