chore(napi): add oxc-parser to benchmarks (#2724)

Closes #2616.

Adds benchmarks for NodeJS NAPI build. Measurement includes `JSON.parse`
of the AST on JS side, since that's how it'll be used 99% of the time.

Benchmarks run against same files as Rust parser benchmarks, so we can
see the overhead of transferring AST to JS.
