Blockchain Provider tree state integration

[mattsse]

Blocked by #8745

The BlockchainProvider providers all provider trait impls and is responsible for fetching requested data such as blocks
Currently this supports access to the blockchaintree:

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

Lines 72 to 73 in 892d5dd

	/// The blockchain tree instance.
	tree: Arc<dyn TreeViewer>,

with #8745 we need to give it access to the in memory state as well.
we need to track:

• highest block on disk
• current head (in tree)
• pending block (current head + 1, if we have the corresponding payload)

Ideally this is some kind of Arc<Rwlock where the internals track the height -> State and state includes block+receipts+state after the block.

this should be an object safe trait that gives access to the in memory blocks and state, the tree service will populate this type with the canonical chain after FCU and is effectively something like

struct InMemoryState {
  blocks: HashMap<Hash, Arc<State>>
  numbers: HashMap<u64, Hash>,
  pending: Option<State>,
}

very similar to what we have in anvil:

TODO

• scaffold trait and type similar to Treeviewer that can provide the range of the canonical chain that is currently stored in memory so the Blockchainprovider knows where to fetch things from
