reverse MemoryOverlayStateProvider block order

[mattsse]

Currently the MemoryOverlayStateProvider expects the list of blocks to be [old -> new]

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

Lines 13 to 14 in c4bf5bb

	/// The collection of executed parent blocks.
	in_memory: Vec<ExecutedBlock>,

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

Line 34 in c4bf5bb

for block in self.in_memory.iter().rev() {

but this is usually populated by walking backwards:

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

Lines 732 to 735 in c4bf5bb

	while let Some(executed) = self.state.tree_state.blocks_by_hash.get(&parent_hash) {
	parent_hash = executed.block.parent_hash;
	in_memory.insert(0, executed.clone());
	}

so it would be more efficient if we'd do [new -> old] so appending a parent block is a simple push
