  CL/Vulkan: Add numeric versioning for extensions
  
  With extended versioning support, the version number of extensions need
  to be reported as well. Using the numeric versioning mode for adding
  supported extensions.
  
  Also, fix the version number for cl_khr_icd and
  cl_khr_extended_versioning extensions.
