cl-post-processor: support wireframe/scaler/wavelet-nr

  * add scaler/wireframe (face detection) testcase in test-pipe-manager
    and gst-xcamfilter. Test command line:
    # test-pipe-manager --format=NV12 --width=1920 --height=1080 \
      --fake-input=input.NV12 --enable-wireframe -p
    # gst-launch-1.0 filesrc location=input.NV12 ! videoparse \
      width=1920 height=1080 format=nv12 ! xcamfilter copy-mode=1 \
      enable-wireframe=true ! queue ! vaapiencode_h264 \
      rate-control=cbr ! qtmux ! filesink location=test.mp4

  * add wavelet-nr testcase in test-pipe-manager and gst-xcamfilter.
    test command line:
    # test-pipe-manager --format=NV12 --width=1920 --height=1080 \
      --fake-input=input.nv12 --wavelet-mode=X -p
    # gst-launch-1.0 filesrc location=input.nv12 ! videoparse \
      width=1920 height=1080 format=nv12 ! xcamfilter copy-mode=1 \
      wavelet-mode=X ! queue ! vaapiencode_h264 rate-control=cbr \
      ! qtmux ! filesink location=test.mp4
