This commit merges the duplicated __detail::__statically_sized and simd::__static_sized_range concepts into a single ranges::__static_sized_range concept within libstdc++. This consolidation reduces code duplication and improves maintainability. The implementation is based on the __statically_sized concept, which avoids instantiating class templates for each possible size value.
