ASoC: SOF: ipc4-pcm: support multiple configs for BE DAIs

Backend DAIs may support multiple audio formats. Modify pipeline
setup to select a suitable configuration based on topology and
frontend DAI runtime configuration.

For sampling rate, if one of the BE DAI configurations has
a sampling rate matching that of FE DAI, configure BE DAI to
this rate.

For sample format, the current code hardcodes DAI copier sample format
to 32bit for both playback and capture pipelines. This is not always
desired, so lift the limitation and set the sample format based on
topology definitions for the copiers. For capture pipelines, we want to
set the BE DAI pipeline format based on topology instead of using the FE
DAI format. This covers the common use-case where BE DAI outputs data at
a higher sample precision and sample width is reduced later in the
pipeline. Instead of hardcoding to 32bit, use the BE DAI copier output
format defined in topology.
