  Vulkan: Shader support for KHR_blend_equation_advanced
  
  Translator can accept the layout qualifiers for the advanced blend
  equation.  No emulation code is currently generated, and ANGLE will
  initially rely on the corresponding Vulkan extension.
  
  Based on change by Brandon Schade <b.schade@samsung.com>
  
  Bug: angleproject:3586
  Test: angle_unittests --gtest_filter=*KHRBlendEquationAdvanced*
