Allow to define comment style

[lukasoppermann]

There is a commentStyle proper in the formatter, however it seems that at least in css this can not be overwritten: https://github.com/amzn/style-dictionary/blob/main/lib/common/formatHelpers/createPropertyFormatter.js#L52

Would be great if this option could be added: https://amzn.github.io/style-dictionary/#/formats?id=cssvariables

options.commentStyle could either be short or none ot it could be a boolean.

I think that makes sense. It sounds like you are looking to turn off comments for specific files, maybe we expose that as an option on file configs?

[lukasoppermann]

Exactly, I want to turn it off. Exposing it like this would be perfect.

Actually, it doesnt support "none", if you do that you might get #ffffff; undefined or something along those lines, should be easy to add though, PR welcome
