Starting with the context Menus for QtQuick.
Add default UI delegates as a subproject. We allow ourselves to use
Qt Quick Controls there for in order to get a nice "out of the box"
experience for things like context menus, dialogs, etc while leaving
the door open for system embedders to override this.

Opting out of the deployment of these QML files is still very primitive
but can be done by passing WEBENGINE_CONFIG+=no_ui_delegates at qmake
time.

Customization of context menus could be done via a qml component, which
is probably best kept in experimental for now while we address its
shortcomings.

This implements adoptNewWindow for QQuickWebEngineView.
The API is only intended to be used through QML to avoid delegating
the QQuickWebEngineViewHandle ownership through a signal parameter.

Another limitation of the implementation is currently to fail the
handle adoption unless it is done synchronously within the
adoptNewWindow call. To support this we would need to delay the call
to WebContentsAdapter::initialize which will leave the adapter
without a client when returning to the event loop and would require
putting null checks everywhere it is used.
So I would prefer to keep the API limited and avoid potential crashes.
If we want to support asynchronous Loader elements or QML files
fetched from the network in the future, the API should be able to
scale to the task once we've adjusted the implementation.

This also adds basic tabs support in the quicknanobrowser example.
The url property is now set imperatively to avoid overwriting the
adopted WebContentsAdapter's loading URL.

The WebEngineWidgets module and the WebEngine QtQuick plugin libraries
already have the RPATH set properly in their headers and the application
won't need to link any symbol directly to the Core library.

Remove the RPATH directive for examples and tests and fix the build issue
by making sure that the link directive isn't passed to dependencies
through the prl or pkgconfig file.

A few changes are necessary to allow fetching textures provided by
the render processes through IPC and bound to their respective GL
context in the GPU process and use them in the QtQuick scene graph.

- Remove the plain color test textures.
- Allow setting the QtQuick QOpenGLContext's handle as the share
  context for all context set as shared in the Chromium GPU process.
  We do this by letting the GpuChannelManager ask us for a
  ShareGroup instance responsible for returning a sharing GL context
  handle.
- Fetch texture IDs from the MailboxManager used by the GPU process
  using the Mailbox given to us in the DelegatedFrameData.
  This is the same mechanism used by Chromium to share textures
  between "client" GL contexts.
- Keep the QtQuick scene graph threads and Chromium in-process GPU
  thread separate. The complicated part of merging those two
  rendering pipelines on the same thread is that it would force Qt
  to also use only one thread for rendering. For the moment we will
  try to synchronize those threads together instead.
- Lock the Qt SG thread while waiting for resource sync points.
  Do so by posting a callback to the Chromium GPU thread and wait
  until the sync point of every resource has been retired by the
  producing contexts.
- Acknowledge the delegated from once QtQuick swapped the GL buffers
  instead of right after we added the frame to the scene graph.
  This fixes some issues where the textures for the previous frame
  would already be released as Chromium was producing the new frame.

There are still a few issues regarding synchronization that have to
be fixed, especially when Qt triggers the rendering of a new frame
while Chromium is starting to produce the next frame.

Note: To enable it we still need to pass the following command switches:
--enable-delegated-renderer --enable-threaded-compositing --in-process-gpu

This exposes loadProgress in both widget and quick webengineviews.
However, the progress will not change until we get an upstream change
in Chromium where the content LoadProgressChanged API is exposed to all
ports, not just Android. The upstream change is
https://src.chromium.org/viewvc/chrome?revision=221010&view=revision



Once we get that change, you'll see the widget example browser start to
paint a blue progress rectangle in the background of the URL bar. Also,
a progress bar was added to the quicknanobrowser, but it will be stuck
at 0 for now.

Adds a favicon API modelled after the WebKit2 QQuickWebView API, but
using an http(s) URL instead of a custom protocol, because there's no
icondatabase yet.

The icon URL lingers even when a new load is committed, until the load
finishes. It might be more prudent to clear the icon when committing a
new load, but I opted to let the app take care of that detail if
desired. Many browsers show a spinner instead of the favicon while
loading, for example.

There's no widget API implementation for favicons yet, because that API
only makes sense if we have a full-fledged icon database (case in
point: QWebEngineSettings::iconForUrl()).

This also remove unnecessary directives:

- util.h doesn't need to be added to HEADERS, moc doesn't need to go through it
- MOC_DIR doesn't have to be adjusted anymore
