[Feature] Add nonce filler layer

[onbjerg]

Component

providers, pubsub

Describe the feature you would like

Add a NonceLayer (need a better name) like SignerLayer that queries, using the provider, the latest appropriate nonce for a N::TransactionRequest and fills it if it is missing.

Some notes:

1. This layer would need to be layered on before the SignerLayer (i.e. the request goes through NonceLayer -> SignerLayer -> RootProvider)
2. Take note that transactions might be sent concurrently on the same provider, so this needs to be taken into account (see e.g. the atomics usage in ethers: https://docs.rs/ethers-middleware/2.0.14/src/ethers_middleware/nonce_manager.rs.html#10-16)
3. Ideally the layer would work for multiple addresses (i.e. no need to specify an address in NonceLayer like we did for NonceManagerMiddleware in ethers)
