Title:
  Tabs default behaviour is synchronous, should be async

Status in Ubuntu UI Toolkit:

Status in “ubuntu-ui-toolkit” package in Ubuntu:

Bug description:
  Tabs are often created by developers the following way:

          Tab {
              title: i18n.tr("Simple page")
              page: Page {
                  Label {
                      text: "A label"
                  }
              }
          }

  instead of the lazy loading way that does not penalise app startup:

          Tab {
              id: tab
              title: i18n.tr("Simple page")
              page: Loader {
                  parent: tab
                  anchors {
                      left: parent.left
                      right: parent.right
                      bottom: parent.bottom
                  }
                  source: "MyCustomPage.qml"
                  active: tabs.selectedTab === tab
              }
          }

  This leads to a lot of apps starting slowly. I think we should make
  the default Tab behaviour to be asynchronous.
