Stack overflow and OOM should not be catchable from Wasm
https://bugs.webkit.org/show_bug.cgi?id=282959
rdar://139515612
Reviewed by Justin Michaud and Keith Miller.
According to both the old and new exception specs, stack overflow and
out of memory errors should not be catchable from WebAssembly `catch`
(or similar). However, the exceptions were still marked as catchable
from Wasm, meaning they could trigger incorrect handlers.
