submdspan overloads using std::pair are marked as device-usable

[masterleinad]

Cuda 13.3.0 + C++23 complains about submdspan overloads with std::pair arguments since the constructor has MDSPAN_INLINE_FUNCTION annotations, see

mdspan/include/experimental/__p2630_bits/submdspan.hpp

Lines 24 to 29 in cae4a4e

	template <class ElementType, class Extents, class LayoutPolicy,
	class AccessorPolicy, class... SliceSpecifiers>
	MDSPAN_INLINE_FUNCTION
	constexpr auto
	submdspan(const mdspan<ElementType, Extents, LayoutPolicy, AccessorPolicy> &src,
	SliceSpecifiers... slices) {
