Title: Add CPU feature detection and function dispatcher

This changeset adds helpers to detect and support advanced CPU instruction sets, which allows initialization-runtime selection of highly-optimized code when available.

Also modifies recent SSE3 code in hsMatrix44 to use the dispatcher, as well as the recent SSE3 code in plDXPipeline using ugly temporary macro hax awaiting further expected patches.
