Evaluate unifying zksync transaction logic

[elfedy]

There are many places in foundry-zksync codebase where we deal with zksync transactions and zksync transaction fields. These add the same fields as configuration every time so there might be room to unify the argument definition and some helpers, the same way foundry does with the cli transaction module.

Sample instances where we use this:

• zksync build opts (it is actually semantically wrong to have paymaster params here):

  foundry-zksync/crates/cli/src/opts/build/zksync.rs

  Line 106 in 7ef8c11

  pub paymaster_address: Option<Address>,

• script args have gasPerPubdata:

  foundry-zksync/crates/script/src/lib.rs

  Line 223 in 7ef8c11

  pub zk_gas_per_pubdata: Option<u64>,

• cast send:

  foundry-zksync/crates/cast/bin/cmd/send.rs

  Line 37 in 7ef8c11

  paymaster_address: Option<String>,

• cast estimate (PR in progress): https://github.com/matter-labs/foundry-zksync/pull/903/files#diff-014b12e44c97400f71f424549afa0d42cfd880fe1d89b9a2792d8bf316411853R17

I started a draft version of this in #999
but there were some constraints to doing it given the changes needed.
Overall, there is an early implementation in that PR that we could use as a base start and some good feedback to continue it.
