`Layout` template parameter of `Spline Builder2D::operator()` does not work for `LayoutStrided`

[EmilyBourne]

Spline Builder2D::operator() has a template parameter Layout, but passing objects with the Layout LayoutStrided leads to an error. The error comes from this line:

ddc/include/ddc/kernels/splines/spline_builder_2d.hpp

Line 560 in f664a53

m_spline_builder_deriv1(

as the 1D version:

ddc/include/ddc/kernels/splines/spline_builder.hpp

Lines 471 to 472 in f664a53

	template <class Layout, class BatchedInterpolationDDom>
	void operator()(

also assumes that the layout is the same for all arguments and therefore does not like the argument created here:

ddc/include/ddc/kernels/splines/spline_builder_2d.hpp

Lines 554 to 555 in f664a53

	ddc::Chunk spline1_deriv_min_alloc(
	m_spline_builder_deriv1.batched_spline_domain(batched_interpolation_deriv_domain),

I am pretty certain that LayoutLeft will have the same problem.

If you are touching this argument then for Gysela it could also be useful to have a different layout for the values and derivatives (e.g. LayoutRight for the values, and LayoutStrided for the derivatives).
