[API Docs] Invalid parameter values for certain overloads in ObjectAnimator

[pjcollins]

Looking at the generated ObjectAnimator.cs MCW, we seem to have an issue with Javadoc conversion related to certain overloads:
https://gist.github.com/pjcollins/8f5d3d30877dab7f4f58d7324c8e9672

All four overloads contain the same <param> values, regardless of their signature:

/// <param name="target">The object whose properties are to be animated.</param>
/// <param name="xProperty">The property for the x coordinate being animated.</param>
/// <param name="yProperty">The property for the y coordinate being animated.</param>
/// <param name="path">The &lt;code&gt;Path&lt;/code&gt; to animate values along.</param>

This is seemingly causing some issues with a recent API docs update, where we have a handful of invalid <param/> values in:

A similar issue was noted in #931.
