ASoC: SOF: ipc4-topology: Support init_ext_module_data for process modules
Add support for handling init_ext_module_data for process modules, which is going to be used by decoder and encoder type of process modules. The support is generic and it can be extended to other type of process modules or other module types than process with a small update of sof_ipc4_add_init_ext_module_data() function.
