[JSC] Async / Await should not wrap awaited value with one tick
https://bugs.webkit.org/show_bug.cgi?id=241072

Reviewed by Saam Barati.

This patch integrates spec change[1], which removes one level tick count when resolving promise with await.
Previously, regardless of whether the value is promise or not, we are always using resolveWithoutPromise,
but it introduces one tick before the handlers are resolved. The spec change makes it that we can call
performPromiseThen directly if the input value is promise, so we can skip one tick which looks up "then"
and register handlers.

This is beneficial for await performance and it also fixes a bug tested via test262 and attached test due
to the spec change.

We observed performance improvement in async + native promise tests.
