Detect callables and dynamic calls (replaced by 4.1.1)

[spaze]

This release adds new detections listed below, meaning it's possible that you'll see new error messages.

First class callable syntax (#279), for example:

$func = print_r(...);
$func();

Dynamic calls (#276, #278), for example:

$func('foo');
$object->$method();

Test anonymous class usages (#277), for example:

$foo = new class implements ...
$foo = new class extends ...

Anonymous class usages (when the anonymous class extends DisallowedClass for example) were detected before, however the detection is now tested.

Detect callable parameters (#281, #283), for example:

array_map('function', []);
array_map([$object, 'method'], []);
array_map([Class::class, 'staticMethod']);
