Hand convert non-JSDoc at-internal comments

If these are regular comments, then they won't appear in our d.ts files.
But, now we are relying on api-extractor to produce out final merged
d.ts files, so they need to be present in the "input" d.ts files,
meaning they have to be JSDoc comments.

These comments only work today because all of our builds load their TS
files from scratch, so they see the actual source files and their
non-JSDoc comments.
