- Introduce `DummyWithSelfConstructorPromotedParameter` test class to validate the normalization/denormalization.

isGetMethod() recognizes can*() as a valid getter prefix, but
isAllowedAttribute() and getAttributeValue() only support get*, is*
and has*. This causes can*()-derived attributes to be silently dropped
during normalization.

[Serializer] Fix mixed-typed constructor parameters overriding getter-inferred type

| Branch?       | 7.4

This PR fixes a regression introduced in #63401 (7.4.6) where `mixed`-typed constructor parameters incorrectly override the richer type inferred by the property type extractor.

When a DTO has a constructor parameter typed `mixed` but a getter that returns a specific type (e.g., `?MyEntity`), the property type extractor correctly identifies the type from the getter. However, the condition introduced in #63401 was treating `mixed` as a meaningful type constraint and overriding the extractor's type with `Type::mixed()`.

```php
class MyDTO
{
    public function __construct(
        private mixed $entity = null,
    ) {}

    public function getEntity(): ?MyEntity
    {
        return $this->entity;
    }
}
```

With a custom denormalizer registered for `MyEntity`, `denormalize(['entity' => 42], MyDTO::class)` would **no longer invoke the custom denormalizer** in 7.4.6+. The raw integer `42` was passed to the constructor instead of a `MyEntity` instance.

The fix treats `mixed` as carrying no useful type constraint (same as `null`) across all three code paths in `denormalizeParameter()`:

- **`ReflectionTypeResolver` path**: exclude `TypeIdentifier::MIXED` in `isSatisfiedBy()`
- **`ReflectionNamedType` fallback path**: skip override when `TypeIdentifier::MIXED`
- **Legacy `getTypes()` BC path**: skip the whole override block when the parameter type is `mixed`

[Serializer] Fix denormalization of nested array with key types

The nested-array branch in `AbstractObjectNormalizer::validateAndDenormalize` did not propagate `key_type`/`value_type` into the context, unlike the non-nested branch. This caused the parent collection's `key_type` to leak into child properties.

The fix propagates these context keys in `AbstractObjectNormalizer` and advances them to the next nesting level in `ArrayDenormalizer`.
