feat(storage): iterate with a range of vnodes using merge sort in cell-based table

[BugenZhao]

What's changed and what's your intention?

As title. This PR only implements the merge-sort iterator and it's still unused since the vnode always fall back to 0x00 for now. We need to tweak the stateful executors one by one to enable that.

Checklist

• I have written necessary docs and comments
• I have added necessary unit tests and integration tests
• All checks passed in ./risedev check (or alias, ./risedev c)

Refer to a related PR or issue link (optional)

• Close support scanning and iterating with a range of vnodes using merge sort #3432
• Tracking: take vnode into consideration for key ordering #3316
