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).
