Incubator.Dialog - use new Gesture API + refactor

[M-i-k-e-l]

Description

Incubator.Dialog - use new Gesture.Pan API and refactor to a "single" SharedValue.
You should probably look at the file as a whole and not the changes.

As discussed there are a few improvements here:

1. Using the new Gesture.Pan from react-native-gesture-handler.
2. Using a "single" SharedValue for animations (still needed an extra one for the initialTranslation).
3. Not all improvements have been done, prominently: HiddenLocation - consider changing from useState to useSharedValue

Notes:

1. I've left it all in one file, please let me know if you want to fragment it.
2. I had to add a modalVisibility state in order to handle the user changing visible to false (for example pressing a Button \ ListItem that closes the Dialog.
3. All animations are withTiming and with the default duration, we can change it later.
4. I've tested on in a few places, I did not see any bugs we've had before.
5. It looks like that onLayout is called even when the view is hidden (not sure if this is the new API or if I was wrong before), but it should make the opacity flicker a non-issue.
