  centralize basic OS/platform detection functions
  
  We had multiple different places that defined these, and with varying
  naming schemes. Centralize them to be defined in platform_helpers.h.
  
  Also renaming the IsApple(uint32_t) functions to IsAppleGPU(uint32_t) to
  avoid ambiguous meaning: "IsApple" should mean "is Apple-vended OS"
  while "IsAppleGPU" should mean "is Apple GPU vendor ID".
