ASoC: SOF: ipc4-topology: Add prepare op for DAI type widgets

Define the prepare op for the DAI type widgets for IPC4.
The prepare op is responsible for choosing the input/output audio
formats for these widgets based on the runtime PCM params, assigning the
instance ID and updating the total memory usage for the pipelines these
widgets belong to.
