Unfixable ParamNameMismatch when multiple parent classes/interfaces have conflicting param names already

If the parent classes/interfaces already have conflicting param names, this error should not report since it's unfixable

This seems to be the more general case/bug that also affects #11039

I found these snippets:

<?php

class A {
	public function foo( string $a ): void {}    
}

interface B {
    public function foo( string $b ): void {}
}

class M1 extends A implements B {
    public function foo( string $a ): void {}    
}

class M2 extends A implements B {
    public function foo( string $b ): void {}    
}

Psalm output (using commit cdceda0):

ERROR: ParamNameMismatch - 12:33 - Argument 1 of M1::foo has wrong name $a, expecting $b as defined by B::foo

ERROR: ParamNameMismatch - 16:33 - Argument 1 of M2::foo has wrong name $b, expecting $a as defined by A::foo
