Kill floating activities running in the same thread when tapping outside

This change makes all activities from the same app to be finished when we tap outside the halo window. Other apps running in different threads
(floating or not) won't be finished.

Add TYPE_MAGNIFICATION_OVERLAY to InputWindowInfo::isTrustedOverlay()

This fixes a bug where a View with filterTouchesWhenObscured will have
all touches filtered when in magnification accessibility mode. This is
due to magnification being a separate Window over top of the running
Activity. The method onFilterTouchEventForSecurity in View will then
always return false when filterTouchesWhenObscured is enabled on the
View. By adding the magnification Window to the list of Trusted Overlays
we can ensure that touches will work properly with this property enabled.

frameworks/base: Fix change propagating issue

destroyLayer() function has been modified in kk. It is not correct
to propagate the UI corruption fix from jb to kk without considering
the new changes made in kk. This change is to make it align with
the new code in kk.
