[Core] Making regitry able to handle type and non-type template args

[roigcarlo]

📝 Description
*** This is to be merged to core/new-linear-strategy *** first
Modifies the auto-register code to be able to handle classes with type and non-type template arguments (aka ``MyClass<3,Foo>`)

There is a caveat, non-type parameters need to be passed with its type explicitly stated (see ApplyRayCastingInterfaceRecognitionProcess). for example:

template<std::size_t TDim> 
class ...
....
KRATOS_REGISTRY_ADD_TEMPLATE_PROTOTYPE("Processes.KratosMultiphysics", Process, ApplyRayCastingInterfaceRecognitionProcess<TDim>, TDim)

// becomes

KRATOS_REGISTRY_ADD_TEMPLATE_PROTOTYPE("Processes.KratosMultiphysics", Process, ApplyRayCastingInterfaceRecognitionProcess<TDim>, int[TDim])

I need to do this because it is imposible (to the best of my knowldge) to use variadric templates which mix the two types of template arguments. If someone knows how to do it better I am all ears (@sunethwarna, @mpentek, @loumalouomega looking at you guys ;))

Sample output:

template class Kratos::ApplyRayCastingInterfaceRecognitionProcess<2>;
template class Kratos::ApplyRayCastingInterfaceRecognitionProcess<3>;

Becomes:

['ApplyRayCastingInterfaceRecognitionProcess<3>', 'ApplyRayCastingInterfaceRecognitionProcess<2>'] 

Also ping @ddiezrod because you are the only one using this right now :D

There is a conflict already

Shouldn't we add this to the master rather than to my branch?
