Summary [WASM-GC] Add support for struct.new, struct.get and struct.set

Wasm GC proposal introduces structs (https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md#structures) To enhance support of Wasm GC proposal in JSC this patch supports struct.new, struct.get and struct.set operations. These operations have been chosen because it is convenient to test it together and hard to test it separately. Current implementation isn't optimal, at least for B3 and Air tiers, but optimization (replacing runtime call to a load by known offset) for struct.get/set could be easily added as a next step.
