Support instantiating multiple wasm memories
https://bugs.webkit.org/show_bug.cgi?id=277743
rdar://133394285
Reviewed by Yusuke Suzuki.
Add support for instantiating multiple memories in wasm, but not for
executing instructions that use memories other than index 0. This patch
is gated behind a feature flag 'useWasmMultiMemory'.
