Deprecate inherited batched helpers in the Splines

[tpadioleau]

Some functions like

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

Lines 268 to 280 in ca17d55

	template <
	class BatchedInterpolationDDom,
	class = std::enable_if_t<ddc::is_discrete_domain_v<BatchedInterpolationDDom>>>
	explicit SplineBuilder(
	BatchedInterpolationDDom const& batched_interpolation_domain,
	std::optional<std::size_t> cols_per_chunk = std::nullopt,
	std::optional<unsigned int> preconditioner_max_block_size = std::nullopt)
	: SplineBuilder(
	interpolation_domain_type(batched_interpolation_domain),
	cols_per_chunk,
	preconditioner_max_block_size)
	{
	}

are inherited from the previous implementation of the splines where the batched dimensions were in the class templates. As the batched dimensions are now only known during the transformation, these functions/aliases should no longer be necessary. A review over all builders and evaluators should be done.
