Ullrich Schäfer ac39795948 Fixing ActionSheetIOS position after rotation on tablet (#22738)
Summary:
There's been a bug on iOS and iPad that the position of an action sheet using UIActionController isn't updated if the position of its anchor view changes due to rotating the device. A common scenario would be, presenting an action sheet from a right bar button item. Rotating the device will most likely change the bar button's X coordinate. The action sheets arrow would still point to the old position due to how it has been implemented so far.

I used also reduced some code duplication between `-showActionSheetWithOptions` and `-showShareActionSheetWithOptions:` while at it.

Changelog:
----------
