arbitrum: Return filtered address records from TxFilterer.CheckFiltered

[MishkaRogachev]

Part of NIT-4645
Pulled in by OffchainLabs/nitro#4653

Return filtered address records from TxFilterer.CheckFiltered so nitro callers (TxPreChecker) can build a filtered-tx report without re-querying the statedb. gasestimator.Run propagates records only on the ErrArbTxFilter branch.

Pull request overview

This PR extends Arbitrum transaction address-filtering plumbing so callers can obtain the set of filtered address records directly from gas estimation execution, avoiding re-querying the StateDB when state.ErrArbTxFilter is raised (per NIT-4645 / nitro#4653 context).

Changes:

• Change core.TxFilterer.CheckFiltered to return ([]filter.FilteredAddressRecord, error) instead of just error.
• Update eth/gasestimator.Run / internal run to return filtered address records when the failure is state.ErrArbTxFilter, while keeping existing behavior for other errors.
• Adjust internal call sites (e.g., execute) to accommodate the new run return signature.

The exported Run function’s doc comment doesn’t start with the function name, which breaks standard Go doc conventions and can cause lint/doc tooling to miss it. Consider rewriting the comment so the first sentence begins with "Run" and still mentions that filtered address records are returned when filtering trips.
