fix(state-transition): enforce valid eth1 withdrawal credentials

[calbera]

State Transition Changes:

• Ignore creation of validators with a non 0x01 byte prefix in their withdrawal credentials
• In statedb ExpectedWithdrawals only convert Credentials to Address if we know for sure it has the 0x01 byte prefix (to avoid erroring out)

No explicit backwards compatibility handling technically required since on bartio and boonet we do not encounter any deposits with a non 0x01 byte prefix in their withdrawal credentials

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

I have a major concern about handling of deposit with wrong credentails. I think we should skip them, not fail the whole block

[abi87]

not sure we should err here. Similarly to what we do with faulty signature, I think this deposit should be skipped and the others be duly processed
