This PR adds in weight_only_decode option to int8_dynamic_activation_int8_weight, which when set will use dynamic quantization for matmuls of shape (> 1, x) * (x, n) and weight only quantization for the batch_size=1 case. It also updates generate.py to take in a text file for the prompt, we use this to demonstrate these prefill speedups with sh demo_summarize.sh.
