Refactor: unify scatter API to VmmScatter only

Removed VmmScatterManaged and updated all usages, tests, and docs to use VmmScatter as the sole scatter API. VmmScatterMap now only supports VmmScatter rounds. Updated method signatures to use uint for sizes and improved error handling. Removed managed-specific tests and comments. README clarifies Windows x64-only support. Streamlines and simplifies scatter API for future development.
