Subject: [PATCH] REST API: Allow comments to be created setting the user_agent
 parameter.

As of WordPress 4.3 the `wp_new_comment()` function has been updated to allow the comment_agent value to be set when a comment is created. The comments API endpoint now allows the comment author's user agent to be set when creating a comment.
Also, the `readonly` property on the `author_user_agent` parameter in the schema was removed.

Props rabmalin for the initial patch.
Fixes #38425.
Built from https://develop.svn.wordpress.org/trunk@38864
