This PR includes two fundamental changes to the way we do prop diffing:

  1. Instead of safeguarding against setting read-only reflected DOM properties, it attempts to set the property in a try/catch and falls back to setting an attribute

  2. The codepath for detecting xlink:href / xlinkHref props and applying them via setAttributeNS() is simply removed. This was only ever used for the xlink:href attribute, which was removed from SVG 2. The non-namespaced href attribute works exactly the same way. As a bridging solution, since there are lots of folks using <use xlinkHref="..">, I've retained the code that strips any xlink namespace prefix off of the prop name.

Fixes #2926.
