ipc4: Extend struct ipc4_module_init_ext_init with object array

Adds definition, enums, and bits for adding array of struct
ipc4_module_init_ext_object:s with associated data to struct
ipc4_module_init_ext_init payload. Also adds struct
ipc4_module_init_ext_obj_dp_data as an object to be sent as an object
in the array.
