[Wasm] Add missing exception check after rope resolution
https://bugs.webkit.org/show_bug.cgi?id=315478
Reviewed by Justin Michaud.
JSString::value() can throw an out of memory exception when resolving a rope.
The intoCharCodeArray builtin and the builtins loop in
WebAssemblyCompileOptions::tryCreate continued with the null string instead of
bailing out. Add the missing exception checks.
