title: Does Angular Material have built in autosizing for textareas?
body: <p>I am able to import MatTextareaAutosize from Angular Material, but I see nothing about it in the <a href="https://material.angular.io/components/input/overview" rel="noreferrer">docs</a> and have not found a way to use it.</p>
  
  <p>I expected to use something like this:</p>
  
  <pre><code>&lt;mat-form-field&gt;
      &lt;textarea matInput matAutosize&gt;&lt;/textarea&gt;
  &lt;/mat-form-field&gt;
  </code></pre>
  
  <p>Is there a way to get autosizing text boxes with angular material?</p>
