Port all active C# hardware intrinsics APIs for SSE from SIMD native algorithms (#668)

* Implemented all remaining active SSE intrinsics

* Moved CpuMathUtils' architecture-dependent members into SseIntrinsics

* Implemented all new referenced SSE intrinsics, with software fallbacks, passing unit tests, and performance tests

Note: Performance tests for functions that involve AlignedArray are not implemented.

* Minor clean-up before submitting PR

* Minor changes

* Respond to PR feedback, except for implementing new unit tests (coming soon)

* Respond to PR feedback: Implemented new unit tests
