LEMANS-EVK: Add compress offload playback support for MultiMedia3 (#54)

Browse source 
This change enables compress offload playback support on LEMANS-EVK by
adding a dedicated MultiMedia3 playback subgraph and routing it to the
PRIMARY_MI2S_RX path.

Key changes:
* Added a STREAM_SG_PCM_ADD() entry using the
subgraph-compress-stream-vol-playback.m4 template
* Enabled MultiMedia3 as a playback frontend for PRIMARY_MI2S_RX in
mixer and routing definitions
  * Updated routing to include the 'MultiMedia3, stream2.logger1' path
