<extensionoptions>: Remove dead code

<extensionoptions>: Remove dead code

autosize is no longer used in <extensionoptions> and it adds a lot of complexity.

I eventually want <extensionview> and <extensionoptions> to merge to reduce maintenance
overhead, especially on the <webview>/GuestView team. This dead code makes it harder to reach that objective.

Before I create a bug for this, do you know if there's an existing bug?

I'd put it under 442033. Also I'm guessing there is some test that relies on
this, given the red bots? Normal code lgtm though.
