Add support PHPStan param-closure-this

[Kerigard]

Feature description or problem with existing feature

Some Laravel classes provide the ability to add custom methods via closures, but when using them you have to specify the type for $this every time.

Collection::macro('square', function () {
    /** @var \Illuminate\Support\Collection $this */
    return $this->map(fn ($value) => pow($value, 2));
});

Describe the solution you'd like

The macro method uses the @param-closure-this tag to change the value of $this. If support for this tag is implemented, then you will not have to specify the type using @var.

/**
 * @param-closure-this static $macro
 */
public static function macro(string $name, object|callable $macro)

Additional context

/**
 * @param-closure-this Bar $cb
 */
function doFoo(Closure $cb)
{
    $cb->bindTo(new Bar());
    // ...
}

doFoo(function () {
    // $this is Bar
});

I personally email @bmewburn with something related, and he referenced this issue, he said:

We plan on implementing it but I don't have an ETA for now.

I think we will have this resolved eventually but without an ETA not sure when.
