painteditem: better error message when running cmake on textballoon 

Building the TextBalloon in isolation doesn't make any sense.
Its purpose is to implement a delegate, for the painteditem example to
use, and should therefore only be built as part of the painteditem
project.

To build the example, cmake should be invoked with
examples/quick/customitems/painteditem/CMakeLists.txt as its source
path.

The CMakeLists.txt in examples/quick/customitems/painteditem/TextBalloon
should only be used from another CMakeLists.txt file via the
add_subdirectory() command. If invoked directly it makes sense to print
an error message and stop processing.

Task-number: QTBUG-96806
Pick-to: 6.2
