This patch will implement delegate item recycling in
ListView. The API will be the same as used in TableView, except
that it will be off by default since the behavior of a delegate
that is reused is not compatible with legacy applications
which were not written with this in mind.
Most importantly:
- Component.onCompleted will only be called on a delegate the
first time it's created, and never when it's reused.
- Any user-declared properties in the delegate (that is, not
model roles, index, etc) will not be cleared or updated when an
item is reused. The application must do this manually upon
receiving the pooled or reused signal in the item.
[ChangeLog][ListView] ListView now has support for reusing delegate
items. This can be switched on by setting the reuseItems property of
ListView to true.

The model types are not part of the core QML runtime and should only be
loaded if you explicitly import them. We cannot enforce that in Qt5 as
some of them are available from the QtQml import, but we can change it
in Qt6.

Qt 5.0 beta requires changing the default to the 5.0 API, disabling

compatibility API too, so turn it back on.

We'd like to decrease the default timeout for tests in the Qt Project CI
so that we waste less time waiting for hanging tests.
Tests which genuinely take a long time to run, such as these, should
have their timeout explicitly set in their .pro file.
