The moc generated code does a sanity check that NOTIFY signals actually
exist in the parent class when they cannot be found in the class moc
currently runs on.
The logic there was however too simplistic, and couldn't deal with
signals taking a parameter.
Fix this, and take the opportunity to use a proper static_assert instead
of generating a "normal" compile error.
We do not do any checks for the presence of QPrivateSignal, as the whole
point of QPrivateSignal is that it should be private (and not e.g.
protected).
Moreover, we adjust QMetaProperty::notifySignalIndex to take
single-argument notify methods into consideration as well when
encontering an unresolved notify index.

In order to generate metadata for a class `NS::Class`, moc will
"mangle" its name by turning the colons into underscores. This
however makes the generated name have a double underscore, and
all names with double underscores are reserved.
Instead, replace double colons with another string ("SCOPE").
We are then going to use this mangled name to create other identifiers.
To do so, underscores may get appended and prepended to the mangled name
(e.g. "qt_metadata_" + mangled_name + "_t"). This means that a leading
or trailing underscore in the mangled name would also be problematic;
avoid that as well.
