Audio: TDFB: Tune: Update beamformer blob angles

This change adds to exported blobs for ucm2 usage more angles.
The angles selectable from user space are for stereo capture
+/- 5/15/30/90 degrees. The zero degrees beam is changed to
plus/minus degrees to provide some stereo sensation instead
of mono.
