[Clang] Generalize interp__builtin_ia32_shuffle_generic to handle single op permute shuffles. (#167236) This patch extends `interp__builtin_ia32_shuffle_generic` and `evalShuffleGeneric` to handle both 2-argument and 3-argument patterns, replacing specialized shuffle functions with the unified handler. Resolves #166342
