v5 : - fix the commit message as review(Mark Thompson and Moritz Barsnick)
- change the magic filter numbers 8 with VAProcFilterCount
- check multiple filters because multiple filters aren't supported in
the driver now
v4 : - fix sharpless typo(sharpless -> sharpness)
- when don't support denoise/sharpness, report the error and return
- fix denoise/sharpness params buffer leak in error handle
v3 : fix sharpless mapping issue
v2 : fix filter support flag check logic issue

Subject: [PATCH v5] lavfi/scale_vaapi: add denoise/sharpness support.
add denoise/sharpness support, used scope [-1, 100] as the input
scope.
