  Vulkan: Support gl_SampleMask with non-const index
  
  Add support for access to gl_SampleMask or gl_SampleMaskIn
  with non-constant index. Replace gl_SampleMask with
  ANGLESampleMask and reassign ANGLESampleMask
  to gl_SampleMask in the end.
  
  Bug: angleproject:3588
  Tests: dEQP-GLES31.functional.shaders.sample_variables.sample_mask.
             discard_half_per_pixel.*
             discard_half_per_sample.*
