The sourcemap [`debugId`
proposal](https://github.com/tc39/source-map/blob/main/proposals/debug-id.md)
adds globally unique build or debug IDs to source maps and generated
code, making build artifacts self-identifying.
Support for debug IDs was added to
[`rust-sourcemap`](https://github.com/getsentry/rust-sourcemap/pull/66)
in 2023 and Sentry have made use of this to aid in matching up source
and sourcemap files without having to worry about path mismatches or
release versions.
I want to add debug ID support to Rolldown but it uses `oxc::sourcemap`
so it looks like I need to start here first!
The rolldown plugin hook could return an object map, cast it to string
at node, and decode it has unnecessary json overhead at rust. So here
export an new function to let rolldown could using `JSONSourceMap` to
generate `Sourcemap`.
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.
