[JSC] Cache Table0 buffer and size in JSWebAssemblyInstance
https://bugs.webkit.org/show_bug.cgi?id=298752
rdar://160419088
Reviewed by Yijia Huang.
This patch caches table0's buffer and size in the same way to the wasm memory.
We record weak reference to JSWebAssemblyInstance to Wasm::Table. And it
reports size & buffer update when it happens. This eliminates some
dependent load from Wasm::Table for each CallIndirect sequence. Also
this paves a way to cache this buffer well based on more precise
clobberizing model in wasm.
