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
