Debugger: disable load qml stack action for cdb

Since collecting the qml stack relies on calling functions it has a high
risk of getting stuck in that call at least with Qt 5.15. Never the less
I added the correct function in the cdbextension so when the action
get's re-enabled in the future we already start with an updated
extension.
