  Vulkan: Plumb OpenGL ES commands to AGI/debuggers
  
  Use vkCmd*DebugUtilsLabelEXT() calls to delimit all GLES commands, and
  group them under GLES draw/dispatch calls.  Plumb calls from the EVENT
  macro (for every GL entrypoint) to vkCmd*DebugUtilsLabelEXT() via a
  newly-implemented DebugAnnotatorVk class.  Use a new dirty bit so that
  cached entrypoints are associated with a triggering draw/dispatch
  command.
  
  The DebugAnnotatorVk::beginEvent() method saves a string in a vector
  of all GL commands in ContextVk.  The dirty bit converts the strings
  into begin-end vkCmd*DebugUtilsLabelEXT() pairs.  The
  DebugAnnotatorVk::endEvent() method makes the final
  vkCmdEndDebugUtilsLabelEXT() call for a draw/dispatch command.
  
  Enable the OGL->VK mapping feature by setting
  "angle_enable_trace = true" in GN args.
