Isolate element picker's svg layers from page content
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1226

Related commit:
- 9eb455ab5e

In the previous commit, the element picker dialog was
isolated from the page content. This commit is to also
isolate the svg layers from the page content.

With this commit, there is no longer a need for an anonymous
iframe and the isolated world iframe is now directly
embedded in the page.

As a result, pages are now unable to interfere with any
of the element picker user interface. Pages can now only
see an iframe, but are unable to see the content of that
iframe. The styles applied to the iframe are from a user
stylesheet, so as to ensure pages can't override the
iframe's style properties set by uBO.

Simplify client messaging code
Little-used code from vapi-client.js has been moved
to vapi-client-extra.js. Given that vapi-client.js
is injected in all web pages, this means less dead
code being injected in all pages.

Swathes of code in vapi-client.js was used only in
a few very specific cases, such as when the logger's
DOM inspector is opened or when the "Filter lists"
pane in the dashboard is opened -- and thus to avoid
that little used code to be loaded in every web page
unconditionally, it has been moved to its own
separate file, vapi-client.extra.js.

vapi-client-extra.js is loaded declaratively or
programmatically only where needed.
