Refactor SPMD to HPC; add SIMD source generators

Browse Source 
Major namespace migration from SPMD to HPC across all code, templates, and projects. Introduced Misaki.HighPerformance.HPC.Generator with Roslyn-based source generators for SIMD code (e.g., AVX2), including attribute and method generators. Renamed MultipleAdd to MultiplyAdd in all lanes and updated usages. Added AVX2 utility methods via codegen. Updated tests, benchmarks, and project references to use the new framework. Improved SIMD memory utilities and modernized project files. Removed legacy SPMD project from the solution.
