Fix/dialog animation

WOAUILIB-972
The purpose of this fix is to improve the dialog entrance/exist animation.
On the way I fixed small stuff I found

• In PanResponderView I'm now using View's internal animation prop instead of the Container ternary.
• In DialogDismissibleView I removed unnecessary state update (isAnimating doesn't affect render)

In the Dialog component

• I changed the Modal animationType to "none" so we can have better control over the background fading animation
• I created a separate component, OverlayFadingBackground, with a single purpose - the handle the background fading transition. (Technically, now the background fade animation and the dialog entrance/exit animation happen together.)
• Also, minor tweaks with the animation duration, easing, etc..

I believe we had a bug with that, I cannot remember ATM what it was (I think it was on iOS), I hope our e2e will find it (or it doesn't happen :) ).

Edit: this was before I saw the PR, I'm guessing that not using the Modal's fade can solve that.
Edit 2: regarding the things that are not used anymore: I did not find any bugs, so I hope the added OverlayFadingBackground solved all these issues, nice! With that said, we should run e2e + manual test on the private repo.

The hooks plugin says you are missing animateFading

[ethanshar]

fixed the warnings..
But I gotta say, the plugin is not that smart.
It just blindly check what's being used and ask to add it as a dependency, which sometimes is not really necessary.

I know, and it has bugs sometimes (see AutoLockScrollView, it cannot recognize that not all the props need to be checked), but it did find these which are bugs, I think, so it's worth using IMHO.
