Add a `null safety` check for instances when calling functions (`instances null problems`)

KPHPStorm
already has a check for primitives. We need to expand it and add a check for instances of the class.
Sample code:
<?php
declare(strict_types = 1);
function primitive_types() {
/** @var int|null $type */
$type = null;
primitive_fun($type); // error: Can't pass '?int' to 'int' $var
function primitive_fun(int $var) {
}
}
function instances_types() {
class Cls {
}
/** @var Cls|null $type */
$type = null;
instances_fun($type); // no error or warning
function instances_fun(Cls $var) {
}
}
