Fix top level builds failing with AUTOMOC-related missing moc exe

In top level builds, qt_autogen_tools() needs to be called on any
target that enables AUTOMOC. A previous commit fixed that problem for
the qt_target_qml_sources_example target, but missed also fixing it for
the associated plugin target. Add that missed call here.

More examples that use the common "shared" quick directory have also
since been added, but the step that ensures qt_autogen_tools() was
missed. Add them to the missing step. One of the existing steps also
had a typo, which meant it wasn't handled either, so correct that as
well.
