  Vulkan: Emit SPIR-V 1.4 where available
  
  In preparation for optimizations possible for SPIR-V 1.4.  This change
  makes ANGLE output SPIR-V 1.4 if supported, and SPIR-V 1.3 otherwise.
  It handles the following differences between the two versions:
  
  - OpEntryPoint in SPIR-V 1.4 includes all global variables, as opposed
    to SPIR-V 1.3 where only the Input and Output variables are listed
  - Storage buffers use a dedicated storage class in SPIR-V 1.4
