pw_sys_io: Add facade constraint_setting, docs
Adds a constraint_setting associated with the pw_sys_io facade, and
constraint_values for the backends for this facade provided by Pigweed.
Also documents how this mechanism should be used.
pw_sys_io is just the first facade to receive this treatment: the rest
will be handled in followup CLs.
