  Vulkan: Expose performance counters via extension.
  
  This CL rewrites the Vulkan perf counters test to work in the
  angle_end2end_test suite using the newly exposed AMD extension.
  Note that we implement only a subset of the extension. Instead
  of generating monitors and starting/stopping them we simply
  read back all performance counter data at once using the special
  montior value "0".
  
  The CL also enables these tests on SwiftShader.
