This patch add g/s_selection for MT8173 V4L2 Encoder.
Only output queue support g/s_selection to configure crop.
The top/left of active rectangle should always be (0,0).

Signed-off-by: Tiffany Lin <tiffany.lin@mediatek.com>

v5:
- remove visible_height change to a separate patch
v4:
- do not return -ERANGE and just select a rectangle that works with the
  hardware and is closest to the requested rectangle
- refine v3 note about remove visible_height modification in s_fmt_out
v3:
- add v4l2_s_selection to check constraint flags
- remove visible_height modification in s_fmt_out, it will make v4l2-compliance
  test Cropping fail becuase visible_height larger than coded_height.
