Summary
This reverts #4056 to make HTML comments actual comment trivia. It also attempts to fix the formatting for comments as well, trying to preserve whitespace in the same places that prettier does.
This PR is also the result of a cascading clusterfuck of issues that appeared as a result of making this change, so it may seem a little scatterbrained, and a little difficult to review.
Test Plan
CI should pass. Added new tests, and updated snapshots.
