Support for partially ordered parameter sets in mock object expectations

[laloona]

Follow up from PR 6604.

I changed to API to that:

$mock->expects($this->exactly(4))
    ->method('dispatch')
    ->withParameterSetsInPartialOrder(
        ['pinned' => $a],
        [$b],
        [$c],
        ['pinned' => $d],
    );

So Assert::fixed is removed.
Additional I removed the duplication of the exception.
The index in IndexedParameters is moved to the constructor, so it can't be null now.

I hope the naming for the tests is now more consistent.

I noticed that the @param list<mixed> $parameters is correct. When we enter the construct $parameters are not clearly defined as they represent argument sets.
