feat(primitives): add FoundryTransactionBuilder trait

[mablr]

Motivation

This enables seamless handling of tx requests for all Network impls supported by Foundry. This basically unlocks the last blocker for fully Network generic Cast ! 🚀

It may seem a bit "boilerplate", but I really think this is simplest solution to tackle the specific needs of Cast - don't require tx building/signing pipelines refactor at all. Moreover once integrated we'll be a able to get rid of FoundryTransactionRequest hacky impl, so the net code diff will be negative.

With the new design adding support a new Network simply consist in wiring the supported methods, ie if the network supports EIP-7702, simply re-implement:

• authorization_list()
• set_authorization_list()

Crediting @figtracer as co-author for blob_versioned_hashes methods proposed here : alloy-rs/alloy#3730

Once Alloy 2.0 will be released with new unified eip4844 builder trait alloy-rs/alloy#3600, and Tempo will have it's own TransactionBuilderTempo, the FoundryTransactionBuilder impls will be even simpler i.e per-trait bound blanket impls (TransactionBuilder7702/TransactionBuilder4844/TransactionBuilderTempo). In the meantime let's iterate with this.
