qml runtime tool: support alternate conf; add resizeToItem conf

The qmlscene --resize-to-root feature has always been missing from
the qml runtime tool; however it was already possible to add it by
writing a custom configuration file.  Now we support loading different
configurations from resources as well as from the filesystem, and
the first new configuration being added here is resizeToItem.qml
which provides behavior equivalent to qmlscene --resize-to-root.

When the argument given to --config ends with .qml, by convention
it's to be loaded from the filesystem; whereas configurations from
resources are specified without the .qml extension (to make the
command line shorter).

[ChangeLog][QtQml][qml] The QML Runtime tool now has default behavior
matching qmlscene when the root QML object is an Item: it will be
wrapped in a Window which will resize the Item when the Window is
resized.  But you can alternatively use the --config resizeToItem
option, resulting in the same behavior as qmlscene --resizeToRoot:
resizing the root Item programmatically causes the wrapping Window to
be resized.  Behavior can still be customized in other ways using the
--config option with an external QML configuration file.
