  Vulkan: SPIR-V Gen: Drop dependency to glslang
  
  The SPIR-V gen path is now made default.  Compilation through glslang is
  still supported for debugging, and is enabled on the GLSL* end2end tests
  for smoke testing.  On release builds, glslang is not supported.
  
  To test with glslang, add the following gn arg (only necessary if dcheck
  is disabled):
  
      angle_enable_spirv_gen_through_glslang = true
  
  Then enable the generateSPIRVThroughGlslang feature.  This can be done
  by setting an environment variable:
  
      ANGLE_FEATURE_OVERRIDES_ENABLED=generateSPIRVThroughGlslang ./angle_deqp_gles2_tests
  
  Binary size saving:
  
  - 1.3MB on Linux (SPIR-V gen itself: 240KB)
  - 730KB on Android (SPIR-V gen itself: 140KB)
  
  Perf tests:
  
  - LinkProgramBenchmark.Run/vulkan_compile_single_thread
    * Through glslang:
        truncated mean: 1287033.36
    * Direct SPIR-V Gen:
        truncated mean: 244495.91  (~80% reduction)
  
  - LinkProgramBenchmark.Run/vulkan_compile_multi_thread
    * Through glslang:
        truncated mean: 4565894.83
    * Direct SPIR-V Gen:
        truncated mean: 1158164.10  (~75% reduction)
