Analagous to https://bugs.webkit.org/show_bug.cgi?id=237029 which introduced struct types, Wasm GC support also needs support for array type definitions (https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md#type-definitions). Array representation and operations (allocation, access, etc) will come in later patches.
