leaudio: Implement preferred config update logic

This patch implements the preferred config update logic. When setting
preferred config, we put it into requirements and find the first match
with ase config. After that with this preferred ase config, we could use
that to match with remote pac.

Multi Codec would also benifit from pushing preferred codec into
requirements as in the aidl layer they will try to return stack with the
one matched with preferred config (requirements).
