EglFS: make sure resize events are delivered

Make sure that resize events are delivered when the platform
plugin overrides the geometry set in setGeometry().

This fixes a race condition where a widget was resized to its
sizeHint() while the window was maximized, and the content was
shown scaled on the screen.

The problem is that the widget gets the wrong size from
QWidget::setWindowState() (which calls adjustSize() in order to support
normalGeometry). This size is used to resize the backingStore. When the
QWindow is resized, it calls QEglFSWindow::setGeometry() which corrects the
size to screen()->availableGeometry(), and triggers a GeometryChangeEvent
since the size was corrected.

This ends up in QGuiApplicationPrivate::processGeometryChangeEvent() which
will not send a resize event, since the size has not changed (it is always
availableGeometry()). Therefore the widget is never resized, and the
backingStore remains the wrong size.

Doc: Fix cross-module links

- Remove Active Qt -- it's not really plugin-related
- Add QDoc dependencies
- NOTE: Can't add Qt QML because QDoc would get confused between the
  C++ and QML "Qt" namespaces.
