fix: async-currenttarget/preventdefault doesn’t consider nested scopes

[kurtextrem]

Hi! Thanks for the eslint rules. Really helpful.

We found the following example is not caught by the rules I've updated:

const myHandler = async (e) => {
  await foo()
  dummy(() => bar(e.currentTarget))
}

The reason is, while await is in the scope of myHandler, currentTarget (or preventDefault()) is not. To fix it, we have to walk up the scopes and figure out if a parent scope matches the scope where await was found.

👋 @kurtextrem thanks for the contribution! Would you mind updating the tests with a new example for this case?
