ASoC: sof: ipc4-topology: Add support to sched_domain attribute

Add SOF_TKN_COMP_SCHED_DOMAIN and connect it to struct snd_sof_widget
comp_domain member, with new get_token_comp_domain() function.

The logic is such that if the topology attribute is not present in the
widget node the corresponding IPC4 extension value is taken from the
module's manifest like before. But if the attribute is found and
recognized its value overrides what is there in the manifest.
