BUG: Attributes get warped during proxy building

[nezaniel]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Given we have the following PHP Code:

#[Flow\Proxy(false)]
final readonly class MyValueObject
{
    public function __construct(
        public string $value,
    ) {
    }
}

#[Flow\Proxy(false)]
#[\Attribute(\Attribute::TARGET_METHOD)]
final readonly class MyMethodAttribute
{
    public function __construct(
        public MyValueObject $something,
    ) {
    }
}

#[Flow\Proxy(false)]
#[\Attribute(\Attribute::TARGET_PARAMETER)]
final readonly class MyParameterAttribute
{
    public function __construct(
        public MyEnum $somethingElse,
    ) {
    }
}

class MyController {

    #[MyMethodAttribute(new MyValueObject('whatever'))]
    public function myAction(
        #[MyParameterAttribute(MyEnum::SOME_CASE)]
        MyCommand $command
    ): MyCommandResponse {
    }
}

When I set a MethodPrivilege on that action, so that the myAction method is proxied, the resulting proxy method looks as follows:

    /** 
    * Autogenerated Proxy Method 
    */ 
    #[\...\MyMethodAttribute(\...\MyValueObject::__set_state(array( 
         'value' => 'whatever', 
    ))] 
    public function myAction(\...\MyCommand $command) : \...\MyCommandResponse 
    {
    }

leading to two issues:

• the generated static \MyValueObject::__set_state call is not valid PHP as they are not allowed in attributes. Also, no such method exists anyway.
• the parameter attributes is lost

Expected Behavior

The proxy builder should leave the attributes as they are

Steps To Reproduce

code see above

Environment

- Flow: >=8.3.7
