fix(ios): stop setting masksToBounds for animated borderRadius

cornerRadius alone rounds the view's background visually. masksToBounds
clips children and shadows, which conflicts with shadow animations and
doesn't match RN's default overflow:visible. Let the style system
control masksToBounds via the overflow prop instead.
