miyoo: Enable ALSA audio driver and default to it (#13814)

Browse source 
Enable it as it does not freeze. This provides an audio backend that
can report its buffer status, allowing auto frame skip to work on cores
that support it.

Do not build or include alsathread as it results in choppy audio.
Similarly, leave tinyalsa disabled as it plays back at a higher pitch
and is also choppy.

Change the default sample rate to 32000Hz as the previous default of
32730Hz is derived from the 3DS.
