ASoC: msm: qdsp6v2: Handle additional codec specific metadata

Codec specific  metadata is sent only for first stream in gapless
playback. This causes incorrect configuration to be set for second
stream and distortions are observed due to framedrops in adsp.
Add support to send codec specific format during start of
next stream in gapless.
Add bit rate to wma codec data structure as it can vary between
streams in gapless.
