qqmltableinstancemodel: add setRequiredProperty()

Add a virtual function setRequiredProperty() to
QQmlInstanceModel that we override in
QQmlTableInstanceModel. This function can be called
from QQuickTableView, upon getting the initItem signal,
to assign initial values to any required properties
that the view makes use of.

This patch is added as a preparation for adding selection
support to QQuickTableView (which will make use of
"required property isSelected" on the delegate)
