qmllint: enhance QQuickAttachedPropertyPropagator-reuse warning

From the discussion at QTBUG-127650:

the logic needs to be improved for anything deriving from the propagator

• It still makes sense to warn about read-only accesses to the attached property, because they can't override the value.
• Any write access should however not trigger a warning, as that would defeat the point.

For other attached properties, this still needs some consideration. `ListView` can certainly be reused, but only as long as there is no further ListView in the hierarchy in between. For other attached properties like `Keys`, that might need a bit more investigation (does the position in the item tree affect the event handling?)

Enhance the quicklint plugin such that it can be re-enabled again.
