Add quickfix for missing use block on lambdas

[Wilfred]

Example bad code:

function foo(): void {
  $x = 1;
  $f = function() {
    return $x;
  };
}

The quickfix should add the use (if not already present), and the extra variable.

function foo(): void {
  $x = 1;
  $f = function() use ($x) {
    return $x;
  };
}
