feature request: give the ability to accept cookie file directly from QWebEngineView

[godomainz]

proposing setCookie method to QWebEngineView
example :

loader = QtWebEngineWidgets.QWebEngineView()
loader.setCookie("/path/to/cookie.txt")

setCookie should read the file and use that when loading the url
sample cookie.txt can be created using chrome Cookie-Editor plugin

There is no direct official interface
https://doc.qt.io/qt-5/qwebengineview-members.html

We can do it ourselves.
I will provide a demo later.
