Improve qmlls range formatting. Currently the formatter is performing only indentation and whitespace handling. We can add more option by working on line-by-line writer

– QtC currently only supports auto-indent

Can we achieve full formatting capability in selected range, would it be possible to merge fullformatting / rangeformatting in a single library and have an easier api like format(Node *, Range). 

Some challanges of range formatting having the full formatting capability could be:

– How to handle handle unbalanced selected range (can be potentially resolved by finding the common parent first, then start full formatting)

– Full formatting relies on qmldom api, Comments are changing positions , this can conflict with the selected regions.

– Can range formatter support Normalization mode?
