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.
