Refactor allocation types and improve memory management

This commit renames `AllocationType` to `AllocationOption` across multiple files, enhancing clarity in memory allocation practices. Key updates include:
- Modifications to the `UnsafeArray`, `ParallelNoiseBenchmark`, `Arena`, and `DynamicArena` classes to utilize the new `AllocationOption`.
- Refactoring of the `AllocationManager` and `HashMapHelper` classes to support the new allocation strategy.
- Removal of the `Misaki.HighPerformance.Mathematics` project reference, indicating a restructuring of dependencies.
- Introduction of a new `MathUtilities` class for calculating the smallest power of two, aiding memory allocation strategies.

These changes collectively improve code maintainability and clarity in memory management.
