feat(memory): refactor allocation and add new queue

Refactored memory management by removing safety checks and introducing `MemoryHandle` for centralized tracking. Simplified allocation logic across allocators and enhanced `Dispose` methods for better resource cleanup.

Added `UnsafeChunkedQueue<T>`, a lock-free, dynamically resizing queue with chunk-based memory management, supporting parallel producers and consumers.

Updated unit tests to validate new queue functionality and ensure compatibility with refactored memory logic. Incremented assembly version to 1.6.12.

BREAKING CHANGE: Removed `#if MHP_ENABLE_SAFETY_CHECKS` blocks, altering memory validation behavior.
