Subject: [PATCH] sm7125: configuration for spatial audio

Update audio configuration to enable spatial audio:
- build with spatial audio feature enabled and rondo library
- list spatializer effect in audio effect configuration file
- update audio policy configuration files to declare spatializer output
- declare immersive end point in audio platform configuration

Bug: 237677573
Test: spatial audio playback
