Doc: Combine the extending QML tutorial chapters into a single example

Combine the six examples associated with each tutorial chapter
into a single, top-level example project 'extending-qml', with
subprojects for each of the tutorial chapters.

Clean up the docs, add links, and a note about a warning that
the user may see when running the code in the first chapter.
