feat: add enabled prop to draggable view

[geovie]

Motivation

The PR adds a simple enabled flag to BottomSheetDraggableView which sets the enabled flag on the gesture.
Previously enableContentPanningGesture was accessed via useBottomSheetInternal.

By allowing to set the enabled flag on the component directly it is now possible to use BottomSheetDraggableView even if the enableContentPanningGesture of the BottomSheet is set to false and so BottomSheetDraggableView can be used to only make part of the sheet's content draggable.

Another side effect is the removal of:

const DraggableView = enableContentPanningGesture
     ? BottomSheetDraggableView
     : Animated.View;

which previously caused a remount of the content when enableContentPanningGesture was changed.

thanks for submitting this PR, please address the comment i left

i dont think we need to pass it as props, as it is already read internally from useBottomSheetInternal

[geovie]

This is necessary so that BottomSheetDraggableView can also be used when enableContentPanningGesture of the BottomSheet is set to false, see PR description.

I've added an example DraggableViewExample which showcases the usage.

mmm i see, i think for scalability , i would move the enableContentPanningGesture to each scrollable view instead. but we could go ahead with this temporary solution

Yeah, in my case I need to wrap an external component so the solution of this MR would work better for me...
