llamafile: powerpc: add FP16 MMA path for Q4/Q8 matmul (#19709)

Avoid xvi8ger4pp signed→unsigned bias correction by dequantizing Q4/Q8
inputs to FP16 and using FP16×FP16→FP32 MMA. This removes
post-processing overhead and improves performance.

Performance Impact:
1.5 ~ 2x improvement in PP_Speed for Q4 and Q8 Models,
measured with llama-bench and llama-batched-bench.
Q8 Model: granite-4.0-h-micro-Q8_0.gguf (from huggingface)
Q4 Model: Meta-Llama3-8b Q4 model (generated with llama-quantize from
f32 model)
