libstdc++: Replace numeric_limit with __int_traits in mdspan.

Using __int_traits avoids the need to include <limits> from <mdspan>.
This in turn should reduce the size of the pre-compiled <mdspan>.
Similar refactoring was carried out for PR92546. Unfortunately,

  ./gcc/xgcc -std=c++23 -P -E -x c++ - -include mdspan | wc -l

shows a decrease by 1(!) line. This is due to bits/max_size_type.h which
includes <limits>.

libstdc++-v3/ChangeLog:

	* include/std/mdspan (__valid_static_extent): Replace
	numeric_limits with __int_traits.
	(extents::_S_ctor_explicit): Ditto.
	(extents::__static_quotient): Ditto.
	(layout_stride::mapping::mapping): Ditto.
	(mdspan::size): Ditto.
	* testsuite/23_containers/mdspan/extents/class_mandates_neg.cc:
	Update test with additional diagnostics.
