move QtQuick.Dialogs from qtdeclarative to qtquickcontrols

This will enable using Controls in the QML dialog implementations.
For now, Controls are used only as drop-in replacements for the
Button, Checkbox, and TextField which were custom implementations
in the qtdeclarative module before.

+    It is not recommended to be used directly; it is an implementation
+    detail of \l FileDialog in the \l QtQuick.Dialogs module.
+
+    To use this type, you will need to import the module with the following line:

+    \qmlsignal QtQuick::Dialogs::FileDialog::accepted
+
+    The \a accepted signal is emitted when the user has finished using the
+    dialog. You can then inspect the \a fileUrl or \a fileUrls properties to
+    get the selection.
+
+    Example:
+
+    \qml
+    FileDialog {
+        onAccepted: { console.log("Selected file: " + fileUrl) }
+    }
+    \endqml
