Examples: move widgets/codeeditor into manual tests

It's not a very well written example, using (largely unneed) hacks to
implement what it does. It's also misleading - the syntaxhighlighter
example is a better showcase for building a useful code editor.

Move it to manual tests.

Fixes: QTBUG-111025
Pick-to: 6.5
