[Wasm-GC] Implement packed types in arrays
https://bugs.webkit.org/show_bug.cgi?id=247576
Reviewed by Justin Michaud.
This patch implements support for packed types (i8, i16) in Wasm GC
arrays. Packed types are represented with new entries in wasm.json and
are only allowed for use in StorageTypes, which are a new kind of type
used for struct and array type definition fields.
Packed structs are not yet allowed with this patch.
