Provide interactive help to reflow expressions

[jmarolf]

We want to help the developer restyle their code dynamically. We can present an interface that shows the developer a set of different styles simultaneously and allows them to quickly select the option that looks best.

Tracking Issues

• Formatting rule for columnar formatting
• Comment indentation
• "Wrap" refactorings should be a part of code-style
• Feature request: Allow me to specify a desired max-column that code shoudl be wrapped against.
• I would like a refactor in the C# editor that will reflow a multiline comment at some margin.
• Prettier-style line breaking
• Alignment Refactoring ordering should be stable
