InputFlinger: Add DROP_INPUT feature flags
If a window has the feature DROP_INPUT set, then all touch and
key events directed to the window will be dropped. For touch events,
the events will not go to the window behind it.
The flags are used to enable features that allow for a less trusted
interaction model between apps. See the bug for more details.
