Support template strings for translation in QML files

It would be nice to be able to write translatable string using template literals in QML files like

import QtQuick

Window {
    id: root
    width: 640
    height: 480
    visible: true

    Column {
        Text {
            text: qsTr("Width: %1 Height: %2").arg(root.width).arg(root.height)
        }
        Text {
            text: qsTr(`Width: ${root.width} Height: ${root.height}`)
        }
    }
}

This is currently not possible since the template string is evaluated by the JS interpreter.
We need to research how we can support this.

One possibility is the introduction of a new tag function like explained in https://bugreports.qt.io/browse/QTBUG-127527?focusedId=836985&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-836985
