conf/ucm: bytcr-rt5651: Add mono speaker output profile

Many rt5651 devices only have a single speaker and even though there is
some external mixing done on the PCB, the quality of that mixing is quite
poor and various sounds come out garbled when relying on the on PCB mixing.

Using the codecs builtin mixer to mix left + right to the left output works
much better. This commits adds a new MonoSpeaker.conf output profile which
allows this.
