  CL: Fix entrypoint validation for ICDs
  
  For some OpenCL ICD implementations,
  the clGetPlatformIDs API is left as nullptr
  in the ICD dispatch table. This is because
  the OpenCL ICD Loader instead uses the
  clIcdGetPlatformIDsKHR call instead.
  
  Updating the passthrough code to only
  require checking the clGetPlatformIDs API
  if the platform is not an ICD.
