feat: add flattracer

[0xkrane]

Closes #10991

still wip but creating draft pr to get some guidance on whether this is the right path

some things to note:

• we first convert the config into a FlatCallConfig
• create the inspector using the from_flat_call_config (this change has been proposed here: chore: add from_flat_call_config revm-inspectors#203) , this allows us to use the precompile flags
• then use the inspector to trace the transaction, instead of initializing a default parity tracer since that would ignore the precompile flag

trying to understand if this is the right approach to adding flatcalltracer or if i'm overcomplicating things

this is a good start, we need to replicate what we do here:

reth/crates/rpc/rpc/src/trace.rs

Lines 342 to 358 in 242a3ab

	/// Returns all traces for the given transaction hash
	pub async fn trace_transaction(
	&self,
	hash: B256,
	) -> Result<Option<Vec<LocalizedTransactionTrace>>, Eth::Error> {
	self.inner
	.eth_api
	.spawn_trace_transaction_in_block(
	hash,
	TracingInspectorConfig::default_parity(),
	move |tx_info, inspector, _, _| {
	let traces =
	inspector.into_parity_builder().into_localized_transaction_traces(tx_info);
	Ok(traces)
	},
	)
	.await

and

reth/crates/rpc/rpc/src/trace.rs

Lines 366 to 374 in 242a3ab

	let traces = self.inner.eth_api.trace_block_with(
	block_id,
	TracingInspectorConfig::default_parity(),
	|tx_info, inspector, _, _, _| {
	let traces =
	inspector.into_parity_builder().into_localized_transaction_traces(tx_info);
	Ok(traces)
	},
	);

I think here we can ignore the block reward stuff
