  Vulkan: Remove removeEarlyFragmentTestsOpt flag
  
  * Removed removeEarlyFragmentTestsOptimization and the related
  SPIRV transformation and variables.
  * Removed mUsesEarlyFragmentTestsOptimization.
  * Removed SH_EARLY_FRAGMENT_TESTS_OPTIMIZATION.
  * Merged updateUsesEarlyFragmentTestsOptimization() into
  updateFragmentInoutRange().
