Fix scrollview overflow prop not set with Props 2.0 (#53871)

Summary:
Pull Request resolved: #53871

The props defined in `YogaStylableProps` define the overflow to be set to `Overflow::Visible` by default.

The scroll view initialized the overflow setting to `Overflow.SCROLL`. This meant that Props 2.0 would only set the overflow prop if it was different from Visible, leading to the scroll view not being configured correctly when asking for the overflow to be visible.

This diff assigns the correct initial value to the scrollview overflow setting only when enabling Props 2.0 to avoid any unexpected behavior changes when not using Props 2.0.
