benchmark: pre-generate data set for URL benchmarks
This patch:

- Introduces `common.bakeUrlData` which can be used to pre-generate
  the data set for the URL benchmarks to loop through instead of
  looping over a constant.
- Add the option to use WPT data in benchmarks for better diversity
  in the input
- Add the option to benchmark URL parsing with base URLs (whatwg only)
- Moves the data in `benchmark/fixtures/url-inputs.js` to
  `benchmark/common.js`
