-----------
[JSC] SerializedScriptValue is not carrying memory64 flag
https://bugs.webkit.org/show_bug.cgi?id=321332
rdar://184365775
Reviewed by Yijia Huang.
Memory64 Wasm Memory was not correctly propagating memory64 flag. And
SerializedScriptValue is incorrectly accessing addressType() of non
attached memory, this is not correct. This patch fixes it.
