Add Across Predict withdraw submit support

[pedronfigueiredo]

Summary

This is PR 3 of 4 in the core stack for Predict withdraws over Across.

• Prepends the original Predict withdraw transaction when submitting post-quote Across flows.
• Uses TransactionType.predictAcrossWithdraw for the Across deposit leg.
• Forces 7702 batch submission when the parent withdraw transaction already has an authorization list.
• Estimates final 7702 submit gas when the submit-time batch shape differs from the quote-time batch shape.
• Moves original transaction gas parsing into a shared Across helper used by quote and submit paths.

Note

Medium Risk
Changes Across submission logic for post-quote flows, including conditional EIP-7702 batch handling and new gas-limit estimation paths, which can affect transaction construction and fee behavior.

Overview
Adds Across submit-time support for post-quote Predict withdraw flows by optionally prepending the original transaction to the submitted batch and using TransactionType.predictAcrossWithdraw for the Across leg.

Refactors Across submit to more aggressively choose EIP-7702 batch submission (e.g., when the parent has an authorizationList or when source gas is paid in-token) and to estimate the final 7702 batch gas limit via TransactionController:estimateGasBatch when the submit batch shape differs from what was quoted.

Also centralizes original-transaction gas parsing into getOriginalTransactionGas (used by both quote and submit), and ensures gas-fee-token submits pass gasFeeToken plus excludeNativeTokenForFee. Tests are expanded to cover these new post-quote/7702 edge cases, and the changelog is updated.
