ASoC: SOF: ipc4-topology: add buffer type support

The corresponding IPC4 module of snd_soc_dapm_buffer widget is module
-to-module copier.
The module-to-module copier is a buffer-like component with demuxing
capabilities.
Rename the host_token_list to common_copier_token_list since it will
be used by host copier and module-to-module copier.
The setup callback is almost the same as sof_ipc4_widget_setup_pcm except
the gtw_cfg data, and the free callback is exactly the same as
sof_ipc4_widget_free_comp_pcm. To reduce the duplication, the commit
reuses the setup and free callbacks.
