jetpack: Remove unused JS client components

Did a pass over _inc/client/components looking for things that weren't
used anywhere, and found a bunch:

* components/data/query-connect-url - Last use removed in #8014
* components/data/query-connection-status - Last use removed in 62e9ab0
* components/data/query-modules - Last use removed in bfc40ad
* components/data/query-plugin-updates - Last use removed in #17003
* components/data/query-site-products - Last use removed in #21594
* components/form/* - Didn't check for last use, too many bits. But it
  looks like the `formsy-react` package many of these depended on wasn't
  even installed since #8208.
* components/inline-expand - Last use removed in #6550
* components/jetpack-dialogue - Last use removed in #16518
* components/jetpack-logo - Last use removed in #20148
* components/jetpack-termination-dialog - Last use removed in #21048
* components/module-settings/index.jsx - Last use removed in #10644
* components/module-settings/inline-module-toggle.jsx - Last use removed
  in #12118
* components/screen-reader-text - Last use removed in #18843
* components/settings - Last use removed in 26315e1, I think
* components/tags-input - Last use removed in #11772

Then there were a few more that were only used from some of the above:

* components/data/query-connected-plugins
* components/module-settings/form-components.jsx
* components/multiple-choice-question
* components/setting-toggle
