* chore: fix cpplint 'include_what_you_use' warnings
Typically by including <memory>, <utility> etc.
* chore: fix 'static/global string constant' warning
Use C style strings instead of std::string.
Style guide forbids non-trivial static / global variables. https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables

* refactor: remove global string variables.
Fix 'global string variables are not permitted' linter warnings
by using the base::NoDestructor<> wrapper to make it explicit that
these variables are never destroyed.
The style guide's take on globals with nontrivial destructors:

* fix: initializer error introduced in last commit
* fix: remove WIP file that was included by accident
* fix: include order
* fix: include order
* fix: include order
* fix: include order, again
* fix: use OOIF for webview tag
* fix: do not call GetNativeView for webview
* fix: OOIPF webview's WebContents is managed by embedder frame
* fix: guest view can not be focused
* fix: clear zoom controller when guest is destroyed
* fix: implement the webview resize event
The webview is no longer a browser plugin with the resize event, use
ResizeObserver instead.
* test: disable failed tests due to OOPIF webview
* fix: embedder can be destroyed earlier than guest
This happens when embedder is manually destroyed.
* fix: don't double attach
* fix: recreate iframe when webview is reattached
* fix: resize event may happen very early
* test: some tests are working after OOPIF webview
* chore: remove unused browser plugin webview code
* fix: get embedder via closure
When the "destroyed" event is emitted, the entry in guestInstances would be
cleared.
* chore: rename browserPluginNode to internalElement
* test: make the visibilityState test more robust
* chore: guestinstance can not work with OOPIF webview
* fix: element could be detached before got response from browser
* Don't use is_offscreen_dummy in MessageBox
* Don't use is_offscreen_dummy in DownloadManagerDelegate
* Don't use is_offscreen_dummy in CommonWebContentsDelegate
* Remove is_offscreen_dummy from NativeWindow
