Fix macOS build requiring Objective-C++17 compilation
static_assert() without a message is a C++17 feature, and
MetalSurface.mm includes C++ headers which use this. Chromium still
defaults to C++14, so we need to explicitly specify that we want to use
the C++17 standard for Objective-C compilation.
