  Vulkan: Remove seamful cubemap emulation
  
  Practically, the Vulkan backend is never expected to run on ES2
  hardware.  It _may_ for WebGL, but seamful cubemap emulation was
  disabled for webgl anyway.

  // MonomorphizeUnsupportedFunctions: Monomorphize functions that are called with
  // parameters that are incompatible with both Vulkan GLSL and Metal:
  //
  // - Samplers in structs
  // - Structs that have samplers
  // - Partially subscripted array of array of samplers
  // - Partially subscripted array of array of images
  // - Atomic counters
  // - samplerCube variables when emulating ES2's cube map sampling
  // - image* variables with r32f formats (to emulate imageAtomicExchange)
  //
  // This transformation basically duplicates such functions, removes the
  // sampler/image/atomic_counter parameters and uses the opaque uniforms used by the caller.
