vd_lavc: by default enable cropping by decoder
While this resolves limitations of lavc decoder crop, it also introduces
artifacts with some of the source files or hwdec.
Depending on chroma sampler it is possible to sample outside the decoder
crop area, pulling dirty pixels into the image. Some decoders left them
zeroed, not black. To fix that we would need specifc solution during
mapping of avframes.
As most of the files require the crop only in bottom/right area, the
AVCodecContext::apply_cropping works ok for those.
For all other cases that require more fancy cropping like 1440x1080+240+0
user can manually set `--vd-apply-cropping=no`.
Limitations of the lavc crop are explained here:
