Add documentation of Custom URL requests

Adds basic documentation to the API. Though the API is still private
we would like people to experiment with it, which is easy if it is
documented.

+    \class QWebEngineUrlRequestJob
+    \brief The QWebEngineUrlRequestJob class represents a custom URL request.
+    \since 5.5
+    \internal
+
+    A QWebEngineUrlRequestJob is given to QWebEngineUrlSchemeHandler::requestStarted() and must
+    be handled by the derived implementations of class.
+
+    A job can be handled by calling setReply().
+
+    The class is owned by QtWebEngine and does not need to be deleted. Note QtWebEngine may delete
+    the job when it is no longer needed, so the signal QObject::destroyed() must be monitored if
+    a pointer to the object is stored.
