src: separate module.hasAsyncGraph and module.hasTopLevelAwait

[joyeecheung]

Clarify the names - hasAsyncGraph means either the module or its dependencies contains top-level await; hasTopLevelAwait means the module itself contains top-level await. Theoratically the former can be inferred from iterating over the dependencies but for the built-in loader it's currently not fully reliable until we eliminate async linking.

Also remove the hasTopLevelAwait method - we can simply put it on the module wrap for source text modules right after compilation.
