Rename previous_global_slot to genesis_slot in compatible

[Sventimir]

Explain your changes:

• For the genesis ledger export (as described in [RFC] Genesis ledger export #14213) to succeed, we need runtime configs of the Mainnet and berkeley to be as compatible as possible. Thus porting 2be03bf to compatible to avoid conflicts.

Explain how you tested your changes:

• Run the node, exported the fork ledger.
• Run the CI.

Checklist:

• Dependency versions are unchanged
  • Notify Velocity team if dependencies must change in CI
• Modified the current draft of release notes with details on what is completed or incomplete within this project
• Document code purpose, how to use it
  • Mention expected invariants, implicit constraints
• Tests were added for the new behavior
  • Document test purpose, significance of failures
  • Test names should reflect their purpose
• All tests pass (CI will check this if you didn't)
• Serialized types are in stable-versioned modules
• Does this close issues? List them

• This is a step towards closing [RFC] Export genesis ledger for hard fork. MinaFoundation/mina#95

Make it a draft until #14271 lands and solves the conflicts with berkeley.

This PR is now stale, and the issue was handled a different way. The test runs with the other method have been successful, and compatible will be retired soon, so I'm going to close this.
