1836359 - Switch to weak-ref parent links (instead of strong-refs) for webgpu objects (where possible)

Status: NEW

(Core :: Graphics: WebGPU, task, P3)

Description

[Kelsey Gilbert [:jgilbert]]

Holding strong-refs to parent objects is simple and (when CC traversal is hooked up properly) viable, but it complicates the CC graph more than we need, and also means that e.g. GPUTextures hold open their GPUDevice, even if there's no great way to use a Texture without a reference to its Device.

Instead, we can use weak-refs, reduce CC traversal work, and reduce risk of messing up CC, and also collect orphaned objects more eagerly.

Going to tentatively mark this as being prioritized for after our V1/ride-the-trains milestone.
