Tooling Performance Upgrades

[cgewecke]

Cuts command and test startup times in half. For the test:fast command saw ~15sec improvement and slower test commands should see even greater gains.

PR:

• Upgrades hardhat to 2.9.3: (Contains a 2X improvement in forked test speeds)
• Upgrades solidity-coverage to 0.7.21 (Cuts ~2 seconds from command startup times)
• Upgrade ts-node to 10.7.0
• Adds swc-core for typescript
  • This is a rust-lang compilation engine with ~25% speedup
• Skip typescript typechecking where irrelevant to command (ex: compile)
• Skip unnecessary typechain compilation of files in the external/artifacts folder for most commonly used commands.
  • typechain (correctly) uses incremental generation for the regular artifacts
  • we rarely add anything to external and it's types are (incorrectly) regenerated for every command
