overlookmotel c7f1d48c0e perf(sourcemap): keep local copy of previous token in VLQ encode (#4596) 
In source map VLQ encoding, keep local copy of previous `Token`, rather than looking up up from `tokens`.

On a local benchmark of just VLQ encoding, this change produces 6% performance increase (benchmarked on MacBook Pro M1).

The sourcemap implement port from 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().
