  D3D11: Handle multi-view Draw* calls
  
  Because the ANGLE_multiview extension uses instancing to multiply
  geometry for each view, Draw* calls with an active multiview program
  have to be handled in the follwing way:
  1) Convert non-instanced Draw calls to their instanced versions.
  2) Multiply the number of instances in an instanced Draw call by the
  number of views.
  The patch also applies the viewport offsets to the viewport and scissor
  rectangle and propagates the computed viewports and scissors to the
  D3D11 runtime.
