Allow passing different arguments to different postprocessors

* Also deprecated --sponskrub-args

Closes: https://github.com/ytdl-org/youtube-dl/issues/27593
Eg: `--postprocessor-args "VideoConvertor:-c:v h264_nvenc -preset slow"`
Eg: `--postprocessor-args "SponsKrub:-include-selfpromo"`

For backward compatibility, `--postprocessor-args args` is equivalent to:
`--post-processor-args "sponskrub:" --post-processor-args "default:args"`
