NEWT iOS: Support Multi-Touch Events, PixelScale, ..

Note: Two subsequent commit will add some required change in the
native UIWindow/UIView creation methods to actually make the NEWT view being displayed ;-)

The demo 'com.jogamp.opengl.demos.ios.Hello' demonstrated a standard NEWT application
running on iOS.
Previous NativeWindow wrap-around demo is preserved in 'com.jogamp.opengl.demos.ios.Hello1'.

Tested on ipad 11'inch arm64 and x86_64 simulation:
- Using GearsES2 demo
- PixelScale 1f, 2f and 0f - last two using max pixel scale
- Touch w/ GearsES2 works:
-- 1 finger rotate
-- 2 finger drag
-- 2 finger pinch-zoom gesture detection
