Fix missing include of <cuda/std/utility>

[miscco]

We are using cuda::std::as_const. However, we relied on a transitive include from <cuda/std/tuple> that will be remove in a future release

Greptile Overview

Greptile Summary

This PR adds a forward-compatibility fix by explicitly including <cuda/std/utility> in type_utils.h. MatX currently uses cuda::std::as_const from this header but was relying on a transitive include from <cuda/std/tuple>. CCCL (CUDA C++ Core Libraries) will remove this transitive dependency in an upcoming release, which would break compilation. The explicit include ensures the code continues to work when downstream dependencies change their internal include structure. Additionally, the PR includes minor whitespace cleanup (trailing spaces and blank line formatting in comments), which has no functional impact but improves code hygiene.

Filename	Score	Overview
include/matx/core/type_utils.h	5/5	Added explicit <cuda/std/utility> include to prevent future compilation breakage when CCCL removes transitive include; cosmetic whitespace cleanup in comments

Confidence score: 5/5

• This PR is safe to merge with minimal risk and represents best-practice defensive programming
• Score reflects a straightforward header dependency fix with zero functional changes to logic; the explicit include is the correct solution for preventing future compilation failures
• No files require special attention; the single modified file contains only the necessary header include and cosmetic whitespace fixes
