The VS Code HTML extension provides many different ways to customize attribute formatting:  It would be great if vscode-xml also had an enum preference providing the same features as well. Maybe the `xml.format.splitAttributes: true/false` preference could be an enum value for the new preference. Issue: https://github.com/redhat-developer/vscode-xml/issues/272 may be a subset of this issue.

We likely have to introduce this preference too:
