efl_input_clickable: increase the time interval for repeated counter

Summary:
The repeated counter in Efl.Input.Clickable_Clicked can be used to
identify double click or triple click.

Previously, the repeated counter in Efl.Input.Clickable_Clicked was
calculated within the time interval 0.1 second.

Now, the time interval for the repeated counter is increased to 0.25
second. It seems that 0.25 second is more appropriate to identify if the
two consecutive clicks should be considered together.
(e.g. considered as double click or triple click)
Moreover, in ecore_event and edje, 0.25 second is already used as a time
interval for double click.

Test Plan:
1. Run Efl.Ui.Button in elementary_test
2. Do double click or triple click the buttons
