[AMDGPU] Change 9 SWMMAC builtins to use 64-bit index (#181246)
There 9 gfx1250 instructions have 64-bit packed index:
- v_swmmac_f16_16x16x128_bf8_bf8
- v_swmmac_f16_16x16x128_bf8_fp8
- v_swmmac_f16_16x16x128_fp8_bf8
- v_swmmac_f16_16x16x128_fp8_fp8
- v_swmmac_f32_16x16x128_bf8_bf8
- v_swmmac_f32_16x16x128_bf8_fp8
- v_swmmac_f32_16x16x128_fp8_bf8
- v_swmmac_f32_16x16x128_fp8_fp8
- v_swmmac_i32_16x16x128_iu8
Intrinsics accept anyint, but builtins are defined with i32 argument.
