This adds a qIsPolishScheduled(QQuickWindow *) overload of qIsPolishScheduled(QQuickItem *) (added in 40d6072bc8a4df0fe1a16025fe30fe653463a446) and deprecates qWaitForItemPolished() (added in 7a3cad0619662b992154e075ec6b840bfc8a46a7) in favor of qWaitForPolish(), which has QQuickItem* and QQuickWindow* overloads. The existing functions that take QQuickItem are useful, but testing Qt Quick applications can be made even easier by allowing users to check if a window has any items that need to be polished. This information is already present (in QQuickWindowPrivate::itemsToPolish), so it's very efficient to check for. This is especially useful now that Qt Quick Layouts using polishing for their layouting, for example, as it's no longer necessary to find individual polishable items in complex hierarchies before proceeding to interact with child items. [ChangeLog][QtQuickTest][QQuickTest] Added QQuickTest::qIsPolishScheduled(QQuickWindow *) and QQuickTest::qWaitForPolish(QQuickWindow *) functions for verifying that updatePolish() was called on one or more items managed by a window. [ChangeLog][QtQuickTest][QQuickTest] Deprecated QQuickTest::qWaitForItemPolished(QQuickItem *). Use the new QQuickTest::qWaitForPolish(QQuickItem *) function instead.
