TelephonyProvider: Improve the performance of deleting Mms.

Triggers "update_threads_on_delete_part" and "mms_words_delete"
run too many times, when delete attachment rows from part
table, it caused Mms application can't deleting lots of MMS
in an acceptable time.

1. Drop the triggers "update_threads_on_insert_part" and
"mms_words_delete".
2. Add code instead of trigger's job to avoid unnecessary
operation, when delete a lot of mms.
