-----------
Update wasm data segment implementation to support multimemory
https://bugs.webkit.org/show_bug.cgi?id=312589
rdar://175020377
Reviewed by Yusuke Suzuki.
Right now the implementation of wasm data segments doesn't know about
multimemory and doesn't have any code to handle a memory index
associated with a data segment. This patch updates it to correctly
handle data segments that specify memory indices other than 0.
Test: JSTests/wasm/stress/data-segment-multimemory.js
