"src/corelib/kernel/qproperty.cpp" documents assignment operators over
`QPropertyBinding` for `QProperty` and `QPropertyAlias`.
Those operators were removed in 638df6138e
and are thus stale.
Similarly, an assignment operator for `QPropertyAlias<T>` over a `T&&`
is documented albeit it was removed in
927647cd03.
Due an incorrect implementation of QDoc, which has now been removed,
with regards to identifying copy/move assignment operators, and the more
superficial and incorrect way in which QDoc binds those kind of elements
to the clang AST, QDoc was unable to report the lack of a binding
declaration for those elements that were removed, producing incorrect
documentation instead.
As of the latest changes to QDoc this will correctly generate a warning.
To avoid the addition of new warnings and remove stale and incorrect
documentation, the document blocks were removed from the file.
