Prevent allocations in Vst3Logger::log_query_interface

String constants will be converted to `std::string` because it's not
constexpr yet, and that will allocate for longer strings. Since this
function only prints something when `YABRIDGE_DEBUG_LEVEL` is set to 2
or higher that seems like a waste.
