[JSC] Fix memory.init's overflow check
https://bugs.webkit.org/show_bug.cgi?id=321056
rdar://184086611
Reviewed by Dan Hecht.
Memory::init's overflow check is using uint32_t, but it is not correct
as memory64 is introduced. We use uint64_t instead. Also we drop dead
Memory::fill / Memory::copy implementations. Use Wasm::memoryCopy /
Wasm::memoryFill.
