eth/tracers: report correct gasLimit in call tracers (#27029)
This includes a semantic change to the `callTracer` as well as `flatCallTracer`.
The value of field `gas` in the **first** call frame will change as follows:

- It previously contained gas available after initial deductions (i.e. tx costs)
- It will now contain the full tx gasLimit value

eth/tracers/native: prevent panic for LOG edge-cases (#26848)
This PR fixes OOM panic in the callTracer as well as panicing on
opcode validation errors (e.g. stack underflow) in callTracer and
prestateTracer.

eth/tracers: add native flatCallTracer (aka parity style tracer) (#26377)
Adds support for a native call tracer with the Parity format, which outputs call frames
in a flat array. This tracer accepts the following options:

- `convertParityErrors: true` will convert error messages to match those of Parity
- `includePrecompiles: true` will report all calls to precompiles. The default
  matches Parity's behavior where CALL and STATICCALLs to precompiles are excluded

Incompatibilities with Parity include:

- Parity removes the result object in case of failure. This behavior is maintained
  with the exception of reverts. Revert output usually contains useful information,
  i.e. Solidity revert reason.
- The `gasUsed` field accounts for intrinsic gas (e.g. 21000 for simple transfers)
  and refunds unlike Parity
- Block rewards are not reported

eth/tracers: use non-threaded tracechain (#24283)
This makes non-JS tracers execute all block txs on a single goroutine.
In the previous implementation, we used to prepare every tx pre-state
on one goroutine, and then run the transactions again with tracing enabled.
Native tracers are usually faster, so it is faster overall to use their output as
the pre-state for tracing the next transaction.

eth/tracers, core/vm: remove time from trace output and tracing interface (#26291)
This removes the 'time' field from logs, as well as from the tracer interface. This change makes the trace output deterministic.  If a tracer needs the time they can measure it themselves. No need for evm to do this.

eth/tracers: small refactor for native tracers (#26196)

eth/tracers: add withLog to callTracer (#25991)
In some cases, it is desirable to capture what is triggered by each trace, when using the `callTracer`. For example: call `USDT.transfer` will trigger a `Transfer(from, to, value)` event.

This PR adds the option to capture logs to the call tracer, by specifying `{"withLog": true}` in the tracerconfig. 
Any logs belonging to failed/reverted call-scopes are removed from the output, to prevent interpretation mistakes.

Fix trace call for inner reverts (#25971)
Inner call reverts will now return the reason similar to the top-level call. Separately, if top-level call is of type CREATE and it fails, its `to` field will now be cleared to `0x00...00` instead of being set to the created address.

eth/tracers: use gencodec for native tracers (#25637)
The call tracer and prestate tracer store data JSON-encoded in memory. In order to support alternative encodings (specifically RLP), it's better to keep data a native format during tracing. This PR does marshalling at the end, using gencodec.

OBS! 
This PR changes the call tracer result slightly:

-  Order of type and value fields are changed (should not matter). 
-  Output fields are completely omitted when they're empty (no more output: "0x"). Previously, this was only _sometimes_ omitted (e.g. when call ended in a non-revert error) and otherwise 0x when the output was actually empty.

eth/tracers: add onlyTopCall option to callTracer (#25430)
This PR allows users to pass in a config object directly to the tracers. Previously only the struct logger was configurable.

It also adds an option to the call tracer which if enabled makes it ignore any subcall and collect only information about the top-level call. See #25419 for discussion.

The tracers will silently ignore if they are passed a config they don't care about.
