Refactor memory management with MemoryHandle

Replaced `SafeHandle` with a new `MemoryHandle` system for improved memory tracking, safety, and leak detection. Updated allocators (`ArenaAllocator`, `HeapAllocator`, `StackAllocator`) and collections (`UnTypedArray`, `UnsafeArray<T>`, `UnsafeBitSet`) to use `MemoryHandle`.

Refactored `AllocationManager` to use `ConcurrentSlotMap` for live allocation tracking and added methods for managing `MemoryHandle` instances. Simplified alignment and padding logic across allocators and collections.

Enhanced performance with optimized memory operations (`MemClear`, `MemSet`, `MemCpy`) and vectorized operations in `MemoryUtility` and `UnsafeBitSet`. Fixed alignment issues in vectorized memory operations.

Updated tests to reflect the new memory management system and added new tests for `UnsafeBitSet` bitwise operations. Enabled `ENABLE_COLLECTION_CHECKS` for debug builds and improved error messages and documentation.

Removed unused `SafeHandle` code and adjusted project configuration to include necessary references.
