  [Wasm-GC] Adjust struct.new opcode
https://bugs.webkit.org/show_bug.cgi?id=249149

Reviewed by Yusuke Suzuki and Justin Michaud.

This patch adds an extra opcode for struct.new that allows it to be used
as either 0xfb01 or 0xfb07. The current draft spec uses 0xfb01 and
implementations currently use 0xfb07.

This allows the use of the spec's decoder in tests and also will allow
running GC spec tests.
