fixes#10948
This PR changes how comment options are interpreted.
`CodegenOptions::comments`, `CodegenOptions::annotation_comments` and
`CodegenOptions::legal_comments` are now independent of each other.
### `CodegenOptions::comments`
Controls printing of normal comments. At present, only some leading
comments are preserved. It does not control legal and annotation
comments.
### `CodegenOptions::annotation_comments`
Controls printing of annotation comments
* jsdoc: `/** jsdoc */`
* pure: `/* #__PURE__ */` and `/* #__NO_SIDE_EFFECTS__ */`
* webpack: `/* webpackChunkName */`
* vite: `/* @vite-ignore */`
* coverage: `v8 ignore`, `c8 ignore`, `node:coverage`, `istanbul ignore`
### `CodegenOptions::legal_comments`
Controls printing of legal comments
* starts with `//!` or `/*!`.
* contains `/* @license */` or `/* @preserve */`
---
Comment generation is also changed:
codegen first builds a comments map by keeping only the needed comments.
Printing functions will then print out comments in their respective
positions.
