[JSC] Wasm table64 JS API interfaces
https://bugs.webkit.org/show_bug.cgi?id=321017
rdar://184053551
Reviewed by Cole Carley.
We fix table64 JS API interfaces,
1. Table.length[1] is defined as AddressValue[2], so it should return
BigInt when table is 64bit. But the current code is not doing so.
This patch fixes it.
2. Table.grow should throw a range error when the specified delta is
exceeding[3].
