ci(benchmarks): benchmark parser with tokens and ESTree tokens conversion

[overlookmotel]

Add benchmarks for:

1. Parsing with tokens.
2. Serializing tokens to ESTree-style JSON.

Neither of these benchmarks needs to be kept indefinitely, but they'll be useful while working on the tokens code. There's a lot of room for optimization.

Footnotes

1. 3 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on c/02-17-feat_oxlint_integrate_shared_estree_tokens_and_remove_ts_fallback (501772e) during the generation of this report, so 67ec9e7 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

Pull request overview

This PR adds two new benchmark functions to measure the performance of parsing with tokens and converting tokens to ESTree-style JSON format. These benchmarks complement the existing parser and ESTree benchmarks and will help optimize the token handling code.

Changes:

• Added bench_parser_tokens to benchmark parsing with token collection enabled
• Added bench_estree_tokens to benchmark ESTree token serialization to JSON
• Added oxc_estree_tokens dependency to the benchmark crate
