Add QML download API

This patch exposes downloadStarted and downloadFinished
signals on the WebEngineProfile to notify about downloads.
The WebEngineDownloadItem exposes a subset of Chromium's
content::DownloadItem functionality.
For now we expose minimal requirements to be able to control
downloads in QML but this can be extended in the future.
This patch also adds a DownloadView to quicktestbrowser
to demonstrate the usage of the new API.
