feat: integrate BlockchainProvider2 in EthNodeLauncher

[fgimenez]

Closes: #9731

There were some references to the concrete type BlockchainProvider in the launcher types, this is now generic over T::Provider.

Also, in the with_blockchain_db method, we need to instantiate the concrete blockchain provider, and the constructors are different for BlockchainProvider and BlockchainProvider2, the latter doesn't take a TreeViewer. Now this is implemented with a closure and the need to create a tree instance outside the ctx methods, once the migration is done this will be simplified.

cool, this makes sense,
the helper trait will go away eventually, for now this is appropriate

the last thing missing here are type hints for

let _builder = NodeBuilder::new(config)
| ____________________^
47 | | .with_database(db)
48 | | .with_types::()

because default is still the regular provider

yep, I've added some comments to keep it in mind 264f027

i've added a call to with_types_and_provider specifying the right provider to use, is that enough? f9332ea

cool, yeah this should do it for now
