QtWidgets: includemocs v2022

This makes mocs_compilation.cpp empty again, removing those moc files
that were added after the last sweep in 2016,
0e6ad27549.

Including moc files directly into their classes' TU tends to improve
codegen and enables extended compiler warnings, e.g. about unused
private functions or fields.
