[JSC] Propagate wasm types from WasmFunctionParser
https://bugs.webkit.org/show_bug.cgi?id=297569
rdar://158644933
Reviewed by Keith Miller.
This patch propagates Wasm types more to each backend from
WasmFunctionParser. The purpose is mainly using isNullable information
from the type so that we can avoid repeated unnecessary null checks
which is already guaranteed via types.
