ALSA: compress: add support to codec params for gapless playback

For gapless playback its possible that each track has different encoding.
Existing code does not allow to set this new codec parameters while
doing gapless playback.

This patch adds new SNDRV_COMPRESS_SET_CODEC_PARAMS IOCTL to allow
userspace to set this new parameters required for new codec.
