Crash Team Racing Nitro-Fueled

Adds macOS support on top of OCTR: Linux-only APIs are replaced, the GPU library is built for macOS with a Metal surface, and online play plus ultrawide support are kept.

A native Windows runtime for the PS4 release that loads the player's own dump, runs the original x86-64 code, reimplements PS4 system libraries, saves, audio and pad input, and renders through shadPS4's Vulkan renderer, with a launcher and experimental online play.
