CarEvsGLSurfaceView supports multiple streams

Because only a single GL context is available globally, it is diffcult
that applications manage GLSurface per each camera. To handle a scenario
with multiple previews on the display, CarEvsGLSurfaceView takes an
array of CarEvsGLSurfaceView.BufferCallback object, which represents a
stream of HardwareBuffer objects, and their desired locations on the
display, and renders contents of HardwareBuffer object at desired
positions.

Bug: 191940626
Test: Launch CarEvsCameraPreviewApp CarEvsMultiCameraPreviewApp and
      confirm both apps are running properly.
