style: Simplify serialisation of BorderCornerRadius when possible.

Closes #18458.

Matches other browsers in test-cases like:

<div id="t" style="border-top-left-radius: 5px 5px"></div>
<script>alert(t.style.borderTopLeftRadius)</script>

(I think it'd be nicer to preserve the original value completely, but not going
to complain given we already do this for all sorts of Rect<T>s and such, and
this is much easier).
