CodeChecker spams us about moc-generated code using std::move()

Most messages from CodeChecker that land in its Teams channel are about std::move() being applied in generated code where it has no effect. It is harmless for the generated code to include the no-op std::move() and adapting the generators to work round this warning does not look like a constructive use of developer time. Can we filter out these warnings, at least from the Teams channel ?

As it stands, these messages hide others and put readers off bothering to check for real issues – the usual problems with attention exhaustion – so they cause issues that may matter to escape attention.
