  [Wasm-GC] Implement packed types in struct fields
https://bugs.webkit.org/show_bug.cgi?id=246981

Reviewed by Justin Michaud.

Adds support for packed types (i8, i16) to Wasm GC struct types.
The implementation is similar to packed array support.

This enables struct.js tests from the GC proposal spec testsuite to run
(from commit e5d10bafbbeec8227de40314edd8f26f0bb69130).

Also updates the test version of wasm.json, which was overlooked in
previous patches.
