SpatializerHelper: Fix device compatibility with spatial audio

Do not consider BT SCO devices as compatible with spatial audio.
This is justified because SCO is mono by nature. It also fixes the
problem of having two devices with the same mac address but conflicting
spatial audio settings.

Bug: 242777739
Test: verify head tracking still works after a phone call
