Re-introduce the default WebView implementation.

The default WebView implementation is a non-functional implementation
and its only purpose is to build the, internal only, module library
when building with MSVC. Technically the module library could be skipped
completely as the QtWebView module only provides a qml interface,
however, that means additional changes would need to be done to the
qml project recipes to make it possible for pure qml plugins to have jar
dependencies.

Task-number: QTBUG-46001
