Remove VmmScatterManaged, unify on VmmScatter API

VmmScatterManaged and all related references have been removed. VmmScatter is now the sole scatter API, with updated method signatures (notably, PrepareRead now takes a uint). VmmScatterMap is no longer generic and only supports VmmScatter. All tests and internal usage have been updated accordingly. Documentation and comments now reflect this simplification, and the README clarifies Windows x64-only support. This unifies and streamlines the scatter API across the codebase.
