Split `oxc_formatter` into:
- `oxc_formatter(_js)`: JS/TS specific formatter, comment handling, sortImports, jsdoc, etc
- `oxc_formatter_core`: Language agnostic IR, printer, etc
The naming convention is different from Biome or Ruff (they do not have `_core`, and `_formatter` is equivalent to the core), but this is because in Oxc, items without `_js` are the default.
As a basic task, I have added `Context` as a generic to all relevant parts to ensure support for multiple languages.
There might still be other components that could be refactored into the core, but I would like to finish them as I implement support for other languages.
Also moved some shared utilities to the core in advance.
The playground minifier was not respecting the transform target option, causing ES features like optional chaining to be used even when targeting older browsers that do not support them.
Closes#16889
part of #13646
## Summary
This PR converts the Control Flow Graph (CFG) functionality in `oxc_semantic` from runtime checks to a compile-time cargo feature, eliminating runtime overhead when CFG is not needed.
## Changes
- Added `cfg` cargo feature to `oxc_semantic/Cargo.toml` with `oxc_cfg` as optional dependency
- Feature-gated all CFG-related code using `#[cfg(feature = "cfg")]`
- Updated `oxc_linter` to enable the `cfg` feature (since it requires CFG)
- Made the `control_flow!` macro work correctly with and without the feature
## Benefits
- **Performance**: Eliminates runtime `Option<CFG>` checks when feature is disabled
- **Binary size**: Smaller binaries for crates that don't need CFG
- **Cleaner API**: CFG methods only available when feature is enabled
## Test Plan
- [x] All existing tests pass with `cargo test -p oxc_semantic --features cfg`
- [x] `oxc_linter` builds and works correctly (it enables the feature)
- [x] Feature is backward compatible - existing code continues to work

this PR moves all of the config resolution for a single file into the `ConfigStore` structure, rather than half existing in `oxc_linter` and half in `oxlint` crates
Part of #5068, suggested by @ematipico and @MichaReiser, where @leaysgur
and I explored using biome formatter as the base and made a success. All
credits to the old Rome and the new Biome team.
This PR is in a boilerplate state where some of the functions are marked
as `todo!()`.
I also made the following changes:
* changed the base to be less generic, removed the `Language` and
`Context` generics
* expanded the formatter lifetime to include an `'ast` lifetime
* added access to the source text and comments
* added a mechanism for tracking and accessing parent ast nodes (done by
our codegen)
* removed most of the unit tests because they no longer compile
* removed the `oxc_prettier` crate
playground side PR: https://github.com/oxc-project/playground/pull/71
I went ahead testing out this. Let me know if this is not the plan.
I think the benefit is that this allows rust-side playground code to
reuse some code from other napi crates, for example, `oxc_napi` and
`oxc_parser_napi`. For now, I started as mostly copying paste it and
replacing `#[wasm_bindgen]` with `#[napi]`, but I also used `oxc_napi`
for `OxcError` which replaced diagnostic serialization code from
playground.
