Subject: [PATCH] libservo: Remove `Opts::webrender_stats` and `-Z wr-stats`
 (#39331)

This option is supported via the WebView API now and you can enable it
in servoshell by pressing `Ctrl` + `F12`. The command-line argument and
`Opts` field are older and I believe are no longer necessary.

Testing: This just removes a redundant command-line option, so no tests.
