  Add multiview performance tests
  
  The patch adds two tests to measure the performance of the
  ANGLE_multiview extension implementation:
  1) The first test renders onto two views by issuing thousands of state
  changes and draw calls. The aim of the test is to stress the CPU.
  2) The second test renders onto two views by drawing with one draw call
  half a million quads with multiple attributes per vertex. The attributes
  are passed to the fragment shader where they are used for computing the
  color. The aim of the test is to stress the GPU's memory system.
  
  The patch also extends the ANGLEPerfTest's functionality to only run
  the benchmark if the necessary extensions are available.
