chore: suppress warning about `static_assert`

Using static_assert without an error string is a C++17 extension (https://en.cppreference.com/w/cpp/language/static_assert)

Adding an empty string suppresses noisy warnings since this header gets included in many places. Alternatively, the assertions could be removed
