Subject: [PATCH] Handle Quickpanel

There are different type of quickpanel as below

 - E_QUICKPANEL_TYPE_SYSTEM_DEFAULT
 - E_QUICKPANEL_TYPE_CONTEXT_MENU
 - E_QUICKPANEL_TYPE_APPS_MENU

Thf FHUB AllApps is quickpanel type applcation and
it is DALi application which does not support AT-SPI.

So if the AllApps is on top, then screen-reader should NOT
consume 'GestureDetected' signal.

Refer to follwoing for more cases;
 - https://github.sec.samsung.net/TizenNativeUI/Graphics/issues/1281

So screen-reader module needs to notify quickpanel state.
