Refactor unsafe collections and benchmarks

Changed the `CollectionBenchmark` class to use unsafe code for improved memory operations and added benchmarks for stack-allocated arrays.
Changed the `ParallelNoiseBenchmark` class to remove the internal `NoiseJob` struct, promoting better organization.
Changed the `AllocationManager` class to remove the lock mechanism for thread safety and simplified the `Reset` method.
Changed the `Arena` and `DynamicArena` structs to include `Initialize` methods for better initialization control.
Changed the `UnsafeArray<T>`, `UnsafeHashSet<T>`, and `UnsafeList<T>` structs to improve element access and management.
Updated the `UnsafeCollectionExtensions` class to enhance usability with new methods for copying and converting collections.
Updated the `MemoryLeakException` class to provide more detailed stack trace information for better debugging.
Removed the usage of `UnsafeHashMap` in `Program.cs` and directly ran the `CollectionBenchmark`.
Added a new `NoiseJob` struct in `NoiseJob.cs` for generating gradient noise using `UnsafeArray<float>`.
Fixed minor typos and improved method signatures throughout the codebase for clarity.
