[WebGPU] Integrate Metal-cpp

https://bugs.webkit.org/show_bug.cgi?id=240746
<rdar://problem/89344870>

Reviewed by Dean Jackson.

Metal-cpp is a low-overhead C++ interface for Metal.
https://developer.apple.com/metal/cpp/

Metal-cpp isn't a library per-se, but is instead just a collection of files which users
are supposed to just copy into their project. This does just that, and hooks up all the
necessary flags and paths and everything.

This uses the "single header alternative" described on that webpage, and creates the
single file as a build step.

Metal-cpp files should not be style-checked.
