perf(engine): create standalone state root task

[rkrasiuk]

Description

Create a standalone state root task that is spawned before block execution starts.

reth/crates/engine/tree/src/tree/mod.rs

Lines 2171 to 2173 in 2fba3c0

	trace!(target: "engine::tree", block=?block.num_hash(), "Executing block");
	let executor = self.executor_provider.executor(StateProviderDatabase::new(&state_provider));

A task should initialize a blinded sparse and subscribe to transaction state stream. As it receives transaction execution results, it should fetch the proofs for relevant accounts from the database and reveal them to the tree.

Then it should update relevant leaves according to the result of the transaction.

A lot of things can be reused from #11154.
