clang-format: [JS] do not wrap @see tags.

Summary:
@see is special among JSDoc tags in that it is commonly followed by URLs. The JSDoc spec suggests that users should wrap URLs in an additional {@link url...} tag (@see http://usejsdoc.org/tags-see.html), but this is very commonly violated, with @see being followed by a "naked" URL.

This change special cases all JSDoc lines that contain an @see not to be wrapped to account for that.
