Add PayloadStore::send_and_resolve helper function

[mattsse]

Describe the feature

currently we have two functions for

reth/crates/payload/builder/src/service.rs

Lines 154 to 165 in f6444b2

	/// Sends a message to the service to start building a new payload for the given payload.
	///
	/// This is the same as [`PayloadBuilderHandle::new_payload`] but does not wait for the result
	/// and returns the receiver instead
	pub fn send_new_payload(
	&self,
	attr: T::PayloadBuilderAttributes,
	) -> oneshot::Receiver<Result<PayloadId, PayloadBuilderError>> {
	let (tx, rx) = oneshot::channel();
	let _ = self.to_service.send(PayloadServiceCommand::BuildNewPayload(attr, tx));
	rx
	}

and

reth/crates/payload/builder/src/service.rs

Lines 117 to 128 in f6444b2

	/// Resolves the payload job and returns the best payload that has been built so far.
	///
	/// Note: depending on the installed [`PayloadJobGenerator`], this may or may not terminate the
	/// job, See [`PayloadJob::resolve`].
	async fn resolve(&self, id: PayloadId) -> Option<Result<T::BuiltPayload, PayloadBuilderError>> {
	let (tx, rx) = oneshot::channel();
	self.to_service.send(PayloadServiceCommand::Resolve(id, tx)).ok()?;
	match rx.await.transpose()? {
	Ok(fut) => Some(fut.await),
	Err(e) => Some(Err(e.into())),
	}
	}

it would be great if we have a function that does this in one go

reth/crates/payload/builder/src/traits.rs

Lines 22 to 26 in f6444b2

	/// Represents the future that resolves the block that's returned to the CL.
	type ResolvePayloadFuture: Future<Output = Result<Self::BuiltPayload, PayloadBuilderError>>
	+ Send
	+ Sync
	+ 'static;

send attributes and resolve right away, returning a future that resolves to the builtpayload
