Hook up global exception handler in Hardhat 3

[kanej]

Sentry services have been added in Hardhat 3. However we have not hooked up the node global exception handler for the command line so that exceptions are reported to Sentry.
We want to take across the same capability as exists in Hardhat 2.

TODO

• Review the approach to global exception handling in HH2
• Port the approach to HH3
• Check with the test Sentry environment that exceptions are coming through

Follow-ups:

• Set up alerting to Slack
  • Only Sentry team admins/moderators can set up alerts and I am not one.
  • The alerting rule should be added here: https://nomic-labs.sentry.io/alerts/rules/?project=4507685793103872&statsPeriod=1h&utc=true
  • It should be similar to the one we have configured for Hardhat v2: https://nomic-labs.sentry.io/alerts/rules/buidler/1079337/details/
• Propagate EDR errors/panics via Hardhat
