Enhance memory management and performance benchmarks

Browse Source 
Added a new configuration setting in `.editorconfig` to sort system directives last and increased the maximum line length to 400 characters.
Added a new static class `MathUtilities` in `MathUtilities.cs` with a method `CeilPow2` for computing powers of two.
Added a new benchmark class `CollectionBenchmark` in `CollectionBenchmark.cs` to measure performance of standard versus unsafe arrays.
Added a new benchmark class `HashCodeBenchmark` in `HashCodeBenchmark.cs` to evaluate hash code generation performance.
Added new utility methods in `UnsafeUtilities.cs` for memory allocation and deallocation, including `Malloc`, `AlignedAlloc`, `Realloc`, and `Free`.
Added a new `AllocationType` enum in `AllocationType.cs` to specify memory allocation types.

Changed the project file `Misaki.HighPerformance.Mathematics.csproj` to target .NET 9.0 and enable implicit usings and nullable reference types.
Changed the `ParallelNoiseBenchmark` class in `ParallelNoiseBenchmark.cs` to improve memory allocation strategies and performance.
Changed memory management in `Arena.cs` and `DynamicArena.cs` to use custom `Malloc` and `Free` functions.
Changed the `IUnsafeCollection` interface in `IUnsafeCollection.cs` to include new methods for resizing collections and obtaining unsafe pointers.
Changed the `UnsafeArray.cs` to improve management of unsafe arrays, including constructor and method updates.
Changed the `UnsafeHashMap` and `UnsafeHashSet` classes to enhance performance and memory management.
Changed the `UnsafeCollectionExtensions` class to provide additional methods for copying elements and converting collections.
Changed the `ObjectPool` class in `ObjectPool.cs` to simplify cleanup and remove auto-cleanup functionality.
Changed job scheduling and worker classes in `JobExtensions.cs` and `JobWorker.cs` to improve job scheduling in a thread pool.

Removed commented-out code in `Program.cs` related to previous testing methods.
Removed auto-cleanup functionality from the `ObjectPool` class.
