Improve in memory range lookups

[mattsse]

currently, these lookups are susceptible to race conditions:

reth/crates/storage/provider/src/providers/blockchain_provider.rs

Lines 196 to 200 in 29dc8fc

	for num in start..=end {
	if let Some(block_state) = self.canonical_in_memory_state.state_by_number(num) {
	// TODO: there might be an update between loop iterations, we
	// need to handle that situation.
	headers.push(block_state.block().block().header.header().clone());

TODO

this should be integrated natively into the

reth/crates/chain-state/src/in_memory.rs

Line 110 in 29dc8fc

pub struct CanonicalInMemoryState {

type so that a range lookup returns either no result, partial results, or full, this can be encapsulated with a helper enum that expresses this, for example the range ends below the lowest block in memory

ref #9999

I can take it.
