So far we could assign QObjects of any type into any QmlListWrapper of
another type. This is UB, since you may be holding the underlying
QQmlListProperty in C++, and it's also not very consistent.
Assign null instead if the type doesn't match and emit a warning.
Likewise, also warn when initializing a list with mismatched elements.
[ChangeLog][QtQml][Important Behavior Changes] Assignments to list
properties in QML are now type-checked. Before you could, for example,
insert a plain QObject into list<Item>, producing undefined behavior.
Now it instead inserts null and warns. In particular, if you assign a
JavaScript array of random objects to a list property, QML will check
each individual element, and insert null as well as warn when
encountering type incompatibilities.

Some list implementations don't accept nullptr object and don't grow the
underlying list. This breaks assumptions made in e.g. unshift() or
set_length(), which increase the size of the list by appending nullptr
objects.
Throw type errors if lists don't come back with the correct size after
the calls to append. For the push method, which has accepted this
behavior for a long time, we only generate a runtime warning and return
the actual length of the list.

The test revealed that the fill() method of JS arrays did not properly
range-check its parameters. Fix that, too.
[ChangeLog][QtQml][Important Behavior Changes] QQmlListProperty behaves
like a JavaScript Array now. You can use map(), reduce(), forEach() etc
on it. This also includes a slight change of behavior to the push()
method. push() now returns the new list length, and it checks the length
to not exceed UINT_MAX.

Previously each test would include and build sources from the shared
folder. Now we make those sources a library, build it once, then have
each test link to it instead.
We also take the opportunity to move some helpers that qtquickcontrols2
had added into the quicktestutils library where it makes sense, and
for the helpers that don't make sense to be there, move them into
quickcontrolstestutils.
We add the libraries to src/ so that they are internal modules built as
part of Qt, rather than tests. That way we can use them in a standalone
test outside of qtdeclarative.
