fix(android): sync animated borderRadius to BorderDrawable

When borderRadius is animated via ObjectAnimator, the BorderDrawable
was not updated, causing borders to render with square corners.
Now setAnimateBorderRadius also calls
BackgroundStyleApplicator.setBorderRadius to keep the border drawable
in sync with the animated corner radius.
