What's changed and what's your intention?

This is a progress towards #15900.

This PR refactors the VirtualNode and VnodeMapping. Logic changes are:

  • Derive vnode count from the input (like the length of a vnode mapping or bitmap), instead of using VirtualNode::COUNT.

Checklist

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

Documentation

  • My PR needs documentation updates. (Please use the Release note section below to summarize the impact on users)

pub const COUNT: usize = 1 << 8;
/// The maximum value of the virtual node.
// TODO(var-vnode): remove this and only keep `MAX_FOR_TEST`
pub const MAX: VirtualNode = VirtualNode::from_index(Self::COUNT - 1);

I think COUNT and MAX mean the same thing. Shall we merge them into one? Or do you plan to do it in the future PRs?

Yes. They are just in different types. Will refactor in future PRs.
