How to use gc to manage resources

I have a handle to a huge tensor (`GTensor`) on the gpu, the size is u64(ptr) + u64(len).

I hope that all other operations will use its reference (`GView`), and if there is no reference, the resource will be recycled by js side gc.

Should I define `GTensor` as `resource` and `GView` as `record`?

I'm not sure about the implementation of wasm-gc, and how to reclaim this resource at runtime.

Is there a best practice for gc resources?

Or the gc proposal has not been implemented, and I should wrap it internally as `Rc>`?
