feat(oxc_codegen): preserve annotate comment (#3465)
1. Copy tests from
efa3dd2d8e/internal/bundler_tests/bundler_dce_test.go (L3833-L3971)
2. Add option to preserve annotate comment like `/* #__NO_SIDE_EFFECTS__
*/` and `/* #__PURE__ */`

9ee962add8 feat(transformer): support from_babel_options in TransformOptions (#3301)
Move `BabelOptions` to Transformer. The `output.json` is a standard babel configuration. We can reuse BabelOptions to read [babel.config.json](https://babeljs.io/docs/configuration#babelconfigjson) or our configuration(maybe oxc.config.json)

The current `from_babel_options` implementation is copied from the `transform_options` in `test_case.rs`, which I'll completely reimplement next

2064ae9e0a refactor(parser,diagnostic): one diagnostic struct to eliminate monomorphization of generic types (#3214)
part of #3213

We should only have one diagnostic struct instead 353 copies of them, so we don't end up choking LLVM with 50k lines of the same code due to monomorphization.

If the proposed approach is good, then I'll start writing a codemod to turn all the existing structs to plain functions.

---

Background:

Using `--timings`, we see `oxc_linter` is slow on codegen (the purple part).

![image](https://github.com/zkat/miette/assets/1430279/c1df4f7d-90ef-4c0f-9956-2ec3194db7ca)

The crate currently contains 353 miette errors. [cargo-llvm-lines](https://github.com/dtolnay/cargo-llvm-lines) displays

```
cargo llvm-lines -p oxc_linter --lib --release

```

It's totalling more than 50k llvm lines, and is putting pressure on rustc codegen (the purple part on `oxc_linter` in the image above.

---

It's pretty obvious by looking at https://github.com/zkat/miette/blob/main/src/eyreish/error.rs, the generics can expand out to lots of code.

It seems like we need to rebuild the scopes and symbols while

feat: add oxc sourcemap crate (#2825)
The sourcemap implement port from
[rust-sourcemap](https://github.com/getsentry/rust-sourcemap), but has
some different with it.

- Encode sourcemap at parallel, including quote `sourceContent` and
encode token to `vlq` mappings.
- Avoid `Sourcemap` some methods overhead, like `SourceMap::tokens()`
caused extra overhead at common cases. Here using `SourceViewToken` to
instead of it.

feat: merge features serde and wasm to serialize (#2716)
This PR merges the previous confusing features `serde` and `wasm` into a
single `serialize` feature.

We'll eventually do serialize + type information for both wasm and napi
targets.

`oxc_macros` is removed from `oxc_ast`'s dependency because it requires
`syn` and friends, which goes against our policy ["Third-party
dependencies should be
minimal."](https://oxc-project.github.io/docs/contribute/rules.html#development-policy)
