"==" operator now supports different view hierarchies!

1 - Different view hierarchies

Before the == wasn't working if views weren't on the same Z-index in the view hierarchy.
It was blind taking the first argument's superview.
Now the == operator is smart enough to grab the closest common ancestor 🤓

2 - Reflexivity

The way it was before, the == operator wasn't reflexive.
Meaning

view.Width == contentView.Width
contentView.Width == view.Width

were not generating the same constraint behind the hood.
Mathematically speaking this was quite misleading.

Thanks to fix we can write interchageably :

avatar.Top == photo.Top + 10
photo.Top + 10 == avatar.Top

3- Re-opening Layout([array]) overload

Some needed it for dynamic layout so it's back :)
