There are use cases of webview where the container holding the webview is not
actually destroyed first, instead just webview gets removed from DOM, in such
situations the browser process map is not updated accordingly and holds reference
to stale guest contents, and any window operations like scroll, resize or keyboard
events that has to chain through browser embedder will lead to UAF crash.

* feat: add support for node / preloads in subframes
This feature has delibrately been built / implemented in such a way
that it has minimum impact on existing apps / code-paths.
Without enabling the new "nodeSupportInSubFrames" option basically none of this
new code will be hit.
The things that I believe need extra scrutiny are:
* Introduction of `event.reply` for IPC events and usage of `event.reply` instead of `event.sender.send()`
* Usage of `node::FreeEnvironment(env)` when the new option is enabled in order to avoid memory leaks. I have tested this quite a bit and haven't managed to cause a crash but it is still feature flagged behind the "nodeSupportInSubFrames" flag to avoid potential impact.

* feat: add support preloads in subframes for sandboxed renderers
* spec: add tests for new nodeSupportInSubFrames option
* spec: fix specs for .reply and ._replyInternal for internal messages

* chore: clean up reply usage
* chore: fix TS docs generation
* chore: cleanup after rebase
* chore: rename wrap to add in event fns
* refactor: remove -new-contents-created event
Chromium expects us to take ownership of WebContents in AddNewContents,
we should not create V8 wrapper in WebContentsCreated, otherwise we
would have WebContents being managed by 2 unique_ptr at the same time.
* refactor: make CreateAndTake take unique_ptr
* perf: use an internal module resolver instead of relative requires
* perf: memoize the results of getting exported Electron properties
* perf: make internal module changes consistent across sandboxed / bundled files
* 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
* add did-frame-navigate event to WebContents, pass http response code to it and did-navigate
* docs for frame routing id related api changes on WebFrame and WebContents
* expose WebFrame#routingId and pass it to WebContents frame specific events along with frameProcessId; add WebContets.did-start-navigation event
* fix compilation error on ia32 Windows
* Persist defaults to webPreferences object to JS land can read the inferred values instead of just user defined values
* Test inherited default propogation
* Refactor to remove coupling from fetching values and defaults
* Test description type
* Fix up tests
