[PyQt] PyQt5 support for QtWebEngine (for QML WebEngineView)?

Works as in you can actual load a WebEngineView in QML?  When I set that
attribute I'm still left with the qml import error:

QQmlApplicationEngine failed to load component
file:///home/russ/pcode/qedms/examples/WEV.qml:3 module "QtWebEngine" is
not installed

Although I now see what you were talking about with
QtWebEngine.initialize() not being specifically required, looking at the
attribute it affects (AA_ShareOpenGLContexts) I can see that it isn't the
problem here.  It still seems like QtWebEngine itself is required, and it
doesn't seem to be present.

In short: I guess I don't need the specific QtWebEngine.initialize method,
but it sure seems like I need QtWebEngine itself in order to use
WebEngineView in QML.
