Right now, the constructor device_atomic_ref(T&) is implicit, which does not match the definition provided in C++20. While this seems harmless, it can break code that relies on this implicit conversion if it switches to using std::atomic_ref, which vecmem may decide to do if C++20 is enabled. This commit makes the constructor explicit so it matches the definitions in the STL.
