Use benchmark.js

[ryanio]

This PR targets merging into #794 to:

• Use vm.runBlock() instead of looping over txs with vm.runTx()
• Use benchmark.js to profile runs
• Use github-action-benchmark to store and visualize data in GH Pages.
• Reduce fixture file from 50 to 15 blocks (80mb -> 30mb)
  • ci set for 10 blocks i think is sufficient for now

Sample output:

Total number of blocks in data set: 15
Number of blocks to sample: 10
Block 9422905 x 5,458 ops/sec ±3.03% (83 runs sampled)
Block 9422906 x 5,603 ops/sec ±3.14% (90 runs sampled)
Block 9422907 x 5,149 ops/sec ±5.38% (81 runs sampled)
Block 9422908 x 5,526 ops/sec ±0.92% (90 runs sampled)
Block 9422909 x 5,394 ops/sec ±0.72% (87 runs sampled)
Block 9422910 x 4,619 ops/sec ±6.22% (81 runs sampled)
Block 9422911 x 4,944 ops/sec ±2.30% (84 runs sampled)
Block 9422912 x 4,713 ops/sec ±1.66% (83 runs sampled)
Block 9422913 x 4,763 ops/sec ±1.28% (86 runs sampled)
Block 9422914 x 4,536 ops/sec ±1.93% (82 runs sampled)

Super cool, the tool suite you figured out with this benchmark action and benchmark.js looks really nice, seems to fit exactly our needs. 😄

[ryanio]

This is now ready for review to merge into #794 and then would like to merge into master.

Looks good
