Joshua Spence 9b8c9d280e Exclude variables used in strings inside closures when checking for undeclared variables
Summary:
Improves upon D13795 to correctly handle variables within strings. Specifically, the  following code currently (incorrectly) warns about `$x` being undeclared:

```lang=php
function some_func() {
  return function ($x) {
    echo "$x";
  };
}
```

It's worth noting that the situation would be improved if XHPAST properly parsed strings (see T8049).

Test Plan: Added test case.
