Get all built-in Actor itests working with fvm-workbench

[aarshkshah1992]

I was able to use the fvm-workbench to emit the actor events we are interested in by running some of the built-in Actor itests to get gas traces for emitting actors events.

However, not all tests pass with the workbench.

See these PRs for the changes we had to make to ref-fvm & built-in Actors to get green itests.
filecoin-project/ref-fvm#1962 (cloned FVM 4.0 and made these changes)
filecoin-project/builtin-actors#1505

We should do a complete workstream to get all built-in Actor itests green with the fvm-workbench. This will involve debugging and fixing the issues highlighted in the above PRs.

I got a bit lost investigating some of this because I was (separate to your efforts) trying to get this to run just to use it as a learning tool. Some things I learned trying to integrate the current ref-fvm and builtin-actors:

• Can't explicitly run cron due to sender checks, so you have to make sure they're implicit, this was mostly done on the integration tests so it's just a matter of finishing that: fix(integration): cron_tick to use implicit executions to avoid sender checks builtin-actors#1506
• fvm-workbench's kernel has a Sha256TruncPaddedFake that's really just a plain Sha2_256, so various CID comparisons fail, I believe this might be the reason for failure noted @ https://github.com/filecoin-project/builtin-actors/pull/1505/files#r1457544263
• Randomness is more complicated now thanks to feat: FVM no longer draws randomness for you builtin-actors#1378 - even though we could extern get_chain_randomness and return what we want here, it still gets passed through a blake2b, so I guess we need to be consistent when setting randomness in params, such as https://github.com/filecoin-project/builtin-actors/blob/2654cf27186488b9ee35d519332ba2d1af26b348/integration_tests/src/util/workflows.rs#L634
• A bunch of awkward changes needed to BenchKernel to adapt to the changes in ref-fvm
  • GasOps is gone, ops integrated into the Kernel now
  • CircSupplyOps is gone, integrated into FilecoinKernel
  • ActorOps has an install_actor()
  • price_list() is now on the Kernel's call_manager
  • SendOps and UpgradeOps are now things, but they are bound to generic K:Kernel
  • Syscalls now need to be handled by the kernel, since Add initial support for pluggable syscalls ref-fvm#1922, so, at least in the incarnation I got to, we get an awkward impl<K> SyscallHandler<K> for BenchKernel<K::CallManager> that does a link_syscalls. You can defer to DefaultFilecoinKernel::<K::CallManager>::link_syscalls(linker) to get that done thankfully, but the actual syscalls themselves aren't publicly exported (fvm::syscalls::filecoin) so intercepting requires that those syscalls link up in the way you need here.
• fvm::engine::EnginePool does new instead of new_default
• fvm::trace::ExecutionEvent::InvokeActor has grown a new property

I'm going to stash my changes for now rather than push a branch because it's quite a mess and this feels like quite a rabbit hole that I probably shouldn't entertain right now!
