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.

* Make gen

fix: eth: use the correct state-tree when resolving addresses (#11387)
We need to always use the state-tree from the tipset _after_ the message
executed. If we use any other state-tree, we might not find the address
we're trying to resolve.

This change also has some implication for pending messages: there's no
guarantee we'll be able to generate a 0x-style address for a pending
native message. So, instead of trying, I've removed support for pending
native messages from the Eth API. Messages from EthAccounts will still
work, and native messages will still show up in blocks/traces, they just
won't show up as "pending". Which should affect exactly nobody.

I'm also taking this opportunity to cleanup some edge-cases:

1. Pass contexts where appropriate.
2. Remove all state access from `ethTxHashFromSignedMessage`.

Part of #11355

fix: eth: correctly encode and simplify native input/output encoding (#11382)
* chore: eth: move & rename input/output encoding functions

These are shared functions, so I'm moving them to the utils library.

* fix: eth: correctly encode and simplify native input/output encoding

When generating eth traces, we encode "native" message inputs/outputs
to "solidity ABI" by formatting the inputs/outputs the same way we do in
FEVM's "handle_native_method". However, we had quite a few bugs with the
implementation:

1. We were right-aligning 64bit values in 256bit words, instead of
left-aligning (as we should given that these values are big-endian).
2. The return-value encoding wasn't correctly handling lengths.

This patch:

1. Fixes those bugs.
2. Deduplicates the logic (we're doing _basically_ the same thing in
both cases).
3. Removes all error paths (these functions can't fail).

ee3cdf0e97 Fix use filecoin addr + other small refactor
After changing in prev commit to use to ethereum addresses the
comparison does not make sense against builtin actors. This
fixes that by storing also the filecoin addresses in each trace

Also renamed filecoin related fields to Filecoin prefix.

Also remove requirement call to InvokeContract needed to come
from a evm actor
