Support Langage Server Protocol for qml QML

Hi,

I understand Qt aims users use QtCreator to write their QML code.

But not every one want to change his editor only for QML.

So I think it would be great if Qt supports Langage Server Protocol to help other editor's community support QML (autocompletion, goto, doc, ..)

I also think, it could help making QML more and more popular if users don't have to change their editor to write qml code.
