Much better comment preservation (#22141)
* Retain comments on (and produce sourcemaps on) the equals token in initializers
* Improved comments/sourcemaps for await, yield, while, and for
* Retain comments on block curly-braces
* Emit comments for if statements
* Improved switch case comment emit
* Improve comment and sourcemap emit for try/catch, throw, and continue statements
* Improve sourcemap emit and comments for with statements
* More accurate sourcemaps+comments emit for new, typeof, void, and delete
* Improve comment emit for element access expressions
* Preserve more comments on imports and exports
* Make function a bit more defensive like other usages of emitTrailingCommentsOfPosition
* Support preserving comments within empty lists
* Handle leading comments of tokens, conditionally indent leading comments
* Stop heuristically sourcemapping tokens
When the transform was trivial it worked, but was unneeded, but when it was complex, it was brittle - best leave source mapping up to the transformers
* Fix unneeded +1
* Tighten up element access comments
* Handle comments on parenthesized expression tokens
* Fix nit
