vulkan: Support APPLE 

- Adds support for compilation on MAC with moltenVK. Note that vulkan does
  not work on MacOS yet. There are two main blockers:-
  1) Texture component swizzles are not supported except for
  RGBA8_UNORM->BGRA8_UNORM.
  2) There is a bug in their SPIR-V -> MSL generator.
  GLSL.std.450.xxxx functions are not implemented which breaks rpcs3
  functionality. Trying to compile a vertex shader will throw because
  unpackHalf2x16 is missing.
