(cherry picked from commit 12f62033)

Remove armv7k since Apple Watch Support has been removed
Add x86_64 for 64bits simulators

This fixes Xcode's troubles finding the Coordinator folder.
Additionally moves the Coordinator folder to Sources since it's not
Shared.

on iPad with iOS 9 and higher shouldAutorotate is never called since all orientations are supported by default when
we support multitasking. This lead to no rotationlock when interfacelock was enabled or a 360 video was played.
We're now using supportedInterfaceOrientations: and lock 360 videos to portrait and for interfacelock we save the current orientation and return it.

lastEuler.pitch was accidentally set twice which resulted in jumping and
removing the screenscale + adjusting the zoomfactor makes panning and zooming more responsive

adjusted Bool properties from nonatomic to assign
turned interfacelock off for 360Videos

Do not use the Euler angles provided by CoreMotion as they are not defined in the same reference frame as libvlc.
