Adding new private non-QtQuick API. This new C++ API makes it possible
to have control over the lower levels of WebKit without going via QML.

This is a first version of the API, enough to show pages on the screen.
Many features are not implemented.

* Target.pri:
* UIProcess/API/qt/raw/qrawwebview.cpp: Added.
* UIProcess/API/qt/raw/qrawwebview_p.h: Added.
* UIProcess/API/qt/raw/qrawwebview_p_p.h: Added.

The tests for the new API are pixel tests. They use QRawWebView to load
html files and generate images, and them compare those images to the ones
in UIProcess/API/qt/tests/html/resources.

* UIProcess/API/qt/tests/html/bluesquare.html: Added.
* UIProcess/API/qt/tests/html/redsquare.html: Added.
* UIProcess/API/qt/tests/html/resources/qwkview_noBackground1.png: Added.
* UIProcess/API/qt/tests/html/resources/qwkview_noBackground3.png: Added.
* UIProcess/API/qt/tests/html/resources/qwkview_paint.png: Added.
* UIProcess/API/qt/tests/qrawwebview/qrawwebview.pro: Added.
* UIProcess/API/qt/tests/qrawwebview/tst_qrawwebview.cpp: Added.

Tools:
