August 2023 milestone: Fuzzing necessary groundwork

[Ekleog-NEAR]

Previous milestone: N/A, see zulip history for the things done in July and before.

• [x] Get all PRs listed in https://github.com/near/nearcore/issues/9310 in a state where upstream has no outstanding nits
• [x] Update our infrastructure so that we can start working on new fuzzers without waiting for upstream projects to merge and release
• [ ] (Aspirational) Start working on fuzzers for host functions

[Ekleog-NEAR]

Our infrastructure is now running with our forks of bolero (for finite-wasm) and clusterfuzz, though the upstream PRs have not landed yet. So the non-aspirational part of the milestone is now complete :)

Actually I just thought that I can use this to also use this issue to document the other stuff (outside of what’s listed here) I’ve worked on during August, so that it’s easier to find than in the zulip weekly sync meeting history only:

• Switched finite-wasm to using cargo-bolero on clusterfuzz
• Madrid offsite
• Hacked on zkwasm
• Enabled github merge queues on nearcore
• Worked on CI RTT, thought of our dual use of buildkite and GHA
• Thought about our security release process
• Discussed the best communication patterns with Hacken

This is a cool idea. Maybe others in @near/contract-runtime might be interested in doing something similar as well.
