Fixes pointer events when using popups and/or modal dialogs.

This commit also adds initial support for fading behind modal dialogs.

Avoid unnecessary local/global capturing since when having global
capture enabled we cannot for example tap icons on statusbar.

The logic how pointer events for popups and modal dialogs shall work:

- Modal dialogs:
    * Shall not close when outside dlg is clicked
    * Shall not allow usage or underlying control with mouse
        * Achieved with SetGloballyCapturing and SetPointerCapture
          in enterModal_sys / leaveModal_sys
- Popups
    * Shall close when the outside popup is clicked
        * Achieved with enabling the SetPointerCapture only for topmost
          popup and canceling it for all underlyuing ones.
        * In addition long tap timer needs to be canceled for underlying
          widgets when opening a pop-up. Otherwise theu get longtap event
          whcih causes unexpected behaviour.

TODOs:
    - Fading does not work correctly when more than two levels of modal
      dialogs are opened.
    - Fading does not work correctly when switching away from app and
      back to it with fast swap window (using menu works)
    - Check if fading should be implemented with MAknFadedComponent and
      TAknPopupFader, in order to support cross-application fading
    - Should popups closes when application loses the focus?
