Adds a new environment variable MOZ_BROWSER_XHTML to change Firefox to load
a modified version of browser.xul as browser.xhtml. Adds the xhtml
namespace to the script tags to make them work.

This commit switches the identity popup to use "Content Blocking" as a top-level section
instead of Tracking Protection, which is now demoted to a category of Content Blocking.
To keep this change halfway reviewable, I avoided renaming variables, classNames, ids, etc.
that use the term trackingProtection if they were otherwise unaffected by this patch. There
will be other patches that can do this in the future

The overlay was responsible for script loading and defining three elements
(bhTooltip, placesCommands, placesContext). In the majority of places where
the overlay was included only part of it was used. To remove the overlay, the
elements were each split into include files and moved into where they
were used. For the scripts, a JS file was added that defines all the lazy
modules and then this script, globalOverlay.js and utilityOverlay.js were
inlined to everywhere that would have included them from the overlay.

The overlay defined two elements (helpMenu, menu_ToolsPopup) for all
platforms and three others (windowMenu, baseMenuCommandSet, baseMenuKeyset)
that were MacOS only. The two all platform elements and windowMenu were only
used once and inlined into browser-menubar.inc. The rest of the MacOS only
elements were conditionally inlined into browser-sets.inc.

We keep the XBL binding around for <content>, <constructor>, and <destructor>. This can
eventually be migrated to a Custom Element once we have platform support, but in the meantime
this is a way to get the many thousands of LOC into a JS class.

There's a lot of overhead to loading scripts from <script> tags in
browser.xul. They're loaded asynchronously, and can't begin loading until
after we begin loading browser.xul. They're loaded using off-main-thread
compilation, which means we need to create and merge a new JS zone for each
script we load that way. They don't benefit from the startup cache at all.
If we load those scripts using the subscript loader, they're loaded from the
preloader cache, and begin loading as early as possible. And they're all
loaded into a single off-thread zone, which means there are less zones to
create and merge. From a quick test, this seems to save about 20-40ms on
Windows ts_paint talos runs.
The main downside is that subscript loader scripts don't benefit from lazy
parsing, so we might wind up increasing memory usage if most of the functions
in those scripts aren't used very often. But we should hopefully be able to
fix that by migrating more browser JS to lazy loading.

This removes the obsolete toolkit directory. A few references to dialogOverlay
have been updated to just used <dialog> directly. The InlineSpellCheckerUI var
has also been moved directly to browser.js and defined as lazy getter.
