chore: upgrade ethereumjs packages

[matthewwalsh0]

Upgrade all @ethereumjs/* packages:

• @ethereumjs/util - ^8.1.0 > ^9.1.0
• @ethereumjs/tx - ^4.2.0 > ^5.4.0
• @ethereumjs/common - ^3.2.0 > ^4.4.0

Necessary to align with @metamask/transaction-controller which requires the latest versions to support EIP-7702 transactions.

Requires @metamask/utils PR.

Minor refactors to support breaking changes, primarily:

• Buffer usage replaced with Uint8Array.
• bufferToHex > bytesToHex
• Transaction Constructor > LegacyTransaction.fromTxData
• TxData > TypedTxData
• getMessageToSign(false) > getMessageToSign
• getMessageToSign(true) > getHashedMessageToSign

Notes

• Using bytesToHex from @metamask/utils rather than @ethereumjs/utils for additional control and performance.
• Intentionally doing the minimum refactors to private methods and existing logic hence the continued use of Buffer.
