Improve FreeList alignment, error handling, and GGX SPMD

Browse Source 
- Increased BlockHeader size, added blockStart, and improved alignment logic in FreeList allocator.
- Changed _MIN_BLOCK_SIZE to 32 and consolidated to a single implementation.
- Updated allocation and free logic for correct pointer alignment and header management.
- MemoryUtility now throws OutOfMemoryException on allocation failure.
- Optimized GGXMipGenerationBenchmark SPMD output with MaskScatter and minor math/cleanup improvements.
- Cleaned up Program.cs and enabled global/test initialization.
- Bumped assembly version to 1.6.19.
