fix: inline anonymous class wrongly handles field as Classname.this

[ewt45]

If option "inline anonymous class" is checked, sometimes the field of the anonymous class is wrongly recoginized as the instance of its parent class, which actually is instance of a random class. This leads to the field being added CLASS_INSTANCE type FieldReplaceAttr and displayed as FieldClassName.this rather than its normal name.

example dex
decompiled code: notice that another is displayed as AnotherClass.this

public class Parent {
    public static Parent test(Class<?> cls) {
        final AnotherClass another = new AnotherClass();
        return new Parent() { // from class: jadxtest.Parent.1
            @Override // jadxtest.Parent
            public String func() {
                return AnotherClass.this.toString();
            }
        };
    }

    public String func() {
        return "";
    }
}

this pr extracts Objects.equals(parentClass, fieldsCls.getClassInfo()), and only add CLASS_INSTANCE replace attr if it is true.
