math_sse: fix calling conventions from Ghidra disassembly verification

Browse Source 
Hooks 1,3 (vecMulMat4, quatMulMat4): thiscall->fastcall. Assembly
confirms EDX is read as a parameter (FMUL [EDX+...]) before any write.
Detour types TC2r->FC3r, AB wrappers abTC2r->abFC3r.

Hook 15 (0x699330): removed entirely. Was misidentified as vectorNormalize
but Ghidra shows it's a vec3 componentwise >= comparison returning u32.
Silicon-only function (not UnitXP), stub already in silicon.zig. Our
normalize implementation would have silently corrupted comparison results.

Also fixed comment accuracy: hook 8 RET 0x4 (not plain RET), hook 14
__thiscall (not __fastcall). Bitmask selection replaces MATH_TEST_HOOK
single-select with proper bit flags. 17 hooks total, mask 0x77FFE.
