ifx compiler issues

[vanakara]

1. nf_cross_attention_layer.f90 (line 25)
   In the interface of the module function cross_attention_layer_cons, the variables "sequence_length", "model_dimension" are declared as intent(in): "integer, intent(in) :: sequence_length, model_dimension, n_heads"
   should the "sequence_length", "model_dimension" variables removed, given that they do not exist in the definition of the function in the contains section?
   ifx (2025) compiler gives an error for this, while gfortan doesn't!

2. nf_cross_attention_layer.f90, nf_self_attention_layer.f90
   compilation errors with ifx are solved if the following interface is added before the contains statement. (is that correct?)

` interface
pure module subroutine backward(self, input, gradient, attention_mask)
!! Self Attention back propagation
!! Returns sum of Query, Key and Value gradients
class(self_attention_layer), intent(in out) :: self
real, intent(in) :: input(:, :)
real, intent(in) :: gradient(:, :)
real, intent(in), optional :: attention_mask(:, :)
end subroutine backward

pure module subroutine forward(self, input)
!! Cross Attention forward propagation
!! Passes input three times into MultiHead Attention
!! Input Shape: (sequence_length, model_dimension)
class(self_attention_layer), intent(in out) :: self
real, intent(in) :: input(:, :)
end subroutine forward

module subroutine init(self, input_shape)
class(self_attention_layer), intent(in out) :: self
integer, intent(in) :: input_shape(:)
end subroutine init
end interface
