[scheduler] Do not use kInternalIPC in modules/sms.

Remove kInternalIPC task type.
- If it's used to bind associated interface, use
  kInternalNavigationAssociated instead.
- If it's used to bind non-associated interface, use the task source
  mentioned in the spec or kInternalDefault if it's not speced.
