Add dedicated dev/local launcher

[mattsse]

Describe the feature

we currently have an unfortunate restriction for the --dev mode (LocalPayloadBuilder):

because of this bound

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

Lines 79 to 82 in 2652ec8

	+ EngineValidatorAddOn<NodeAdapter<T, CB::Components>>,
	LocalPayloadAttributesBuilder<Types::ChainSpec>: PayloadAttributesBuilder<
	<<Types as NodeTypesWithEngine>::Engine as PayloadTypes>::PayloadAttributes,
	>,

we require that this struct

reth/crates/engine/local/src/payload.rs

Line 13 in 2652ec8

pub struct LocalPayloadAttributesBuilder<ChainSpec> {

is: PayloadAttributesBuilder

which made this workaround necessary

reth/crates/engine/local/src/payload.rs

Lines 63 to 67 in 2652ec8

	/// A temporary workaround to support local payload engine launcher for arbitrary payload
	/// attributes.
	// TODO(mattsse): This should be reworked so that LocalPayloadAttributesBuilder can be implemented
	// for any
	pub trait UnsupportedLocalAttributes: Send + Sync + 'static {}

we can fix this problem by

1. not require the struct and instead operate on the trait: PayloadAttributesBuilder
2. however this then requires that we need to obtain an instance of this somehow, so we need to provide this
3. I think the best solution here would be that this becomes another trait smth like trait MaybeDevLauncherAddOn, similar to:

   reth/crates/node/builder/src/rpc.rs

   Lines 582 to 593 in 2652ec8

   	/// Helper trait that provides the validator for the engine API
   	pub trait EngineValidatorAddOn<Node: FullNodeComponents>: Send {
   	/// The Validator type to use for the engine API.
   	type Validator: EngineValidator<<Node::Types as NodeTypesWithEngine>::Engine, Block = BlockTy<Node::Types>>
   	+ Clone;
   	/// Creates the engine validator for an engine API based node.
   	fn engine_validator(
   	&self,
   	ctx: &AddOnsContext<'_, Node>,
   	) -> impl Future<Output = eyre::Result<Self::Validator>>;
   	}

   that returns a trait instance on demand

this way we can make the dev mode launcher smarter.
