Subject: [PATCH] Update C++26 deprecated constructs to ensure future standard
 compliance (#1267)

* Update C++26 deprecated constructs to ensure future standard compliance

I replaced std::is_trivial with a combination of std::is_trivially_default_constructible and std::is_trivially_copyable. Additionally, I added the required comma before the ellipsis in variadic functions to match updated language specifications.

* Some additional is_trivial related changes not found directly when compiling tests in C++26
