edje: add "mask_flags" instruction for "part" block

Summary:
Elementary widgets dealing with Evas Events usually mask event_flags with
EVAS_EVENT_FLAG_ON_HOLD, to show that this event is already handled.
However, widget like Elm_Button, it does not handle EVAS_CALLBACK_MOUSE_DOWN directly,
but it handles Edje_Signal instead, so there's no chance to mask event_flags.
Developers can block event propagation by putting rectangle the very last part of EDC,
but this instruction can help the case making elementary widget with only Edje_Signal handling.
This is not required essentially, so please check the necessity of this function.
