chore:: backport #11609 to the feat/nv22 branch (#11644)

* feat: api: improve the correctness of Eth's trace_block (#11609)

* Improve the correctness of Eth's trace_block

- Improve encoding/decoding of parameters and return values:
  - Encode "native" parameters and return values with Solidity ABI.
  - Correctly decode parameters to "create" calls.
  - Use the correct (ish) output for "create" calls.
  - Handle all forms of "create".
- Make robust with respect to reverts:
  - Use the actor ID/address from the trace instead of looking it up in
    the state-tree (may not exist in the state-tree due to a revert).
  - Gracefully handle failed actor/contract creation.
- Improve performance:
  - We avoid looking anything up in the state-tree when translating the
    trace, which should significantly improve performance.
- Improve code readability:
  - Remove all "backtracking" logic.
  - Use an "environment" struct to store temporary state instead of
    attaching it to the trace.
- Fix random bugs:
  - Fix an allocation bug in the "address" logic (need to set the
    capacity before modifying the slice).
  - Improved error checking/handling.
- Use correct types for `trace_block` action/results (create, call, etc.).
  - And use the correct types for Result/Action structs instead of reusing the same "Call" action every time.
- Improve error messages.

Web3ClientVersion(ctx context.Context) (string, error) //perm:read
// TraceAPI related methods
// Returns an OpenEthereum-compatible trace of the given block (implementing `trace_block`),
// translating Filecoin semantics into Ethereum semantics and tracing both EVM and FVM calls.
//
// Returns traces created at given block
// Features:
//
// - FVM actor create events, calls, etc. show up as if they were EVM smart contract events.
// - Native FVM call inputs are ABI-encoded (Solidity ABI) as if they were calls to a
// `handle_filecoin_method(uint64 method, uint64 codec, bytes params)` function
// (where `codec` is the IPLD codec of `params`).
// - Native FVM call outputs (return values) are ABI-encoded as `(uint32 exit_code, uint64
// codec, bytes output)` where `codec` is the IPLD codec of `output`.
//
// Limitations (for now):
//
// 1. Block rewards are not included in the trace.
// 2. SELFDESTRUCT operations are not included in the trace.
// 3. EVM smart contract "create" events always specify `0xfe` as the "code" for newly created EVM smart contracts.
