Supported native declarative animation api (Web)

Brought the declarative animation api, already implemented on iOS and Android, to the Web. So don't need unmountedStyle, mountedStyle or renderTransition props anymore. The Navigation router translates from the native declarative props to the underlying web 'primitives' on NavigationMotion.

The following Twitter sample declarative animation now runs on Android, iOS and the Web.

<NavigationStack
  customAnimation
  crumbStyle={[
    {type: 'alpha', start: 0},
    {type: 'scale', startX: 0.8, startY: '0.8'},
    {type: 'translate', startX: '5%'},
  ]}
  unmountStyle={{type: 'translate', startX: '100%'}}
