fwb: Add CarbonGestures(1/2)

[preetamswain]

• The origininal purpose of this was to use it for Navigation on devices without hardware buttons that dont want to use a Navbar for whatever reasons.
• Now allows emulating all kind of KeyEvents passed to it by CF, as well as being able to capture screenshots and lauch Apps.
• triggerVirtualKeypress originates from DirtyUnicorns/android_external_DUtils ActionHandler
• Add some point this was based on three-fingers-swipe to screenshot, then got heavily reworked, so credits to ghbhaha and wuxianlin
