perf: move luaalloc into weirdperformance, wire clip SSE hook (1.9x)

Browse Source 
- luaalloc moved from standalone module to weirdperformance sub-module
- ClipPolygonToSinglePlane SSE hook wired up (410->206 cyc, 2.55% CPU)
- Eliminated calling convention wrappers: clip_sse (fastcall),
  bone_sse (thiscall) match hook conventions directly
