[new compiler] Initial support for group properties

This implements support for "font.pixelSize: 24" for example. The representation
in the compile data structure is so that font.pixelSize is short-hand for

font {
    pixelSize: 24
}

which means that inside the braces is a complete object initializer. For that
initializer we create a dedicated CompiledData::Object, which however has its
type name empty. When populating the outer instance then, the "font" property
is read as QQmlValueType (a QObject) and instead of creating a new QObject we
use that value type as instance to run the rest of the QML object initializer
(everything in braces).
