Fix Auto click (dwell timing) the checked option isn't the same as the option before upgrading the OS

Root cause:
After OS upgrade to R, the original logic only check SP key but does not consider the setting enabled key to cause it cannot not show correctly.

Next:
1) accessibility_autoclick_enabled=1 but does not have SP key, customize layout is checked and show the right value
2) accessibility_autoclick_enabled=1 and have SP key, show according items is checked
3) accessibility_autoclick_enabled=0, off button is checked
