feat(android): detect foldables

[m1ga]

currently only for testing

const win = Titanium.UI.createWindow({});
win.open();

console.log("isFoldable: " + Ti.App.Android.isFoldable);

Ti.App.addEventListener("windowState", function(e) {
	console.log("--------------------------------");
	console.log("folding state: " + e.state)
	console.log("folding occlusionType: " + e.occlusionType)
	console.log("folding orientation: " + e.orientation)
	console.log("folding isSeparating: " + e.isSeparating)
	console.log("--------------------------------");
})

• new event windowState that will fire when the window state of a foldable is changing (opening up)
• new property Ti.App.Android.isFoldable that will be true if there is a hinge (so a foldable)

Note:
Not sure if it is an emulator thing or not: it only works when you start the app in the open state. If it is closed it won't attach the listener and shows a warning that the size doesn't match 🤷 And the "closed" state is never fired, only the open and half open state.
Have to do some more tests here.
