Doc: Revamp "Extending QML" examples into a tutorial The examples in the "Extending QML" series were often redundant with the information of the "Writing QML Extensions with C++" tutorial, had outdated code and sometimes had no documentation. The examples that covered topics not mentioned in the first tutorial were revamped into a second "advanced" tutorial extending the first one. The others were removed. The remaining examples were largely based on the same example code of a birthday party. This code was slightly adapted and separated into 7 states, each building upon the previous, with the code change illustrating the associated feature. A tutorial page, in the style of the first one, was added documenting the different QML features and the required code changes in the example project. Links in the documentation from and to the affected pages were update as best as possible. Pick-to: 6.5 Fixes: QTBUG-111033 Change-Id: I9d97e8b32b128c1624d67525996fa14d493909d3 Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io> Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>
