Integrate Node traits into LaunchContextWith

[mattsse]

Describe the feature

It would be nice to have access to the FullNodeComponents and FullNodeTypes traits, so we can also move this into the context:

reth/crates/node/builder/src/launch/mod.rs

Lines 132 to 140 in 5293a2f

	// fetch the head block from the database
	let head = ctx.lookup_head()?;
	let builder_ctx = BuilderContext::new(
	head,
	ctx.blockchain_db().clone(),
	ctx.task_executor().clone(),
	ctx.configs().clone(),
	);

this could be done with a new state type, similar to

reth/crates/node/builder/src/launch/common.rs

Line 685 in 5293a2f

pub struct WithMeteredProvider<DB> {

but with access to the FullNodeTypes trait, either by providing this here

reth/crates/node/builder/src/launch/mod.rs

Line 130 in 5293a2f

.with_blockchain_db().await?;

via with_blockchain_db::<T> and then keep the type T in a phantomType for example.

so we can just call let builder_ctx = ctx.builder_ctx()?

and later by attaching the adapter via fn with_components<N: FullNodeComponents> to the launchcontext with an additional attachment type like WithMeteredProvider

reth/crates/node/builder/src/launch/mod.rs

Lines 168 to 172 in 5293a2f

	let node_adapter = NodeAdapter {
	components,
	task_executor: ctx.task_executor().clone(),
	provider: blockchain_db.clone(),
	};

This way, we can push a ton of setup code currently in fn launch into the context.
