Igor Sheludko f051293f5e [wasm-gc] Make WasmObject a subclass of JSReceiver 
This is a first step towards supporting unwrapped WasmObject objects on
JavaScript side.

In addition this CL
1) introduces Representation::WasmValue which is used for all WasmObject
   fields exposed to JavaScript side.
2) adds creation of meaningful DescriptorArrays for WasmObject's Maps.
