Add option for not setting explicit size

If QML Type is defined, quite often you do not want to set an explicit size for this layer in QML.

There should be an option for not setting an explicit size.

Layers in Photoshop always have an explicit size. In QML items can also have an implicit size (e.g.) text items or controls like a button.

There should be a way in the Photoshop bridge to "hint" that a layer/smart object with a QML type has alreday an implicit size and the layer size can be ignored.
