Subject: [PATCH] Settings API: Allow passing a class to `add_settings_field()`
 via the `$args` array.

While it's possible to target the wrapper element otherwise (currently a `tr`), this deficiency is made especially noticeable when custom code cannot take advantage of what core is doing, such as with avatars in #30168.

props valendesigns.
fixes #28975. see #30168.
