Jan Wassenberg 0f70f285e0 1.1x prefill and decode speedup (attention/activations) 
Optimizations
- Better load-balancing in attention threading
(Previously, clusters were limited by #heads)
- Add MulByConstTo to avoid zero-init
- Parallel activations

Cleanup
- Prepare for RowPtr in A or B
- Pass through thread_id to ops
- Avoid warning in bench_matmul

Jan Wassenberg 343482c7ef 1.02x batch decode speedup: BF16 KV cache 
ops-inl.h: Vectorize Rope(), template
Remove unused MulBy, and extra-arg overloads of MulByConst and Softmax
Fix for DecompressAndZeroPad: ensure second vector filled

Jan Wassenberg e5c81f64a1 Major refactor: clarify query_idx (global) vs qi. Refs #607 
Fix missing pos increment for last prefill and check that in gemma_test.
Thanks to @ufownl for pointing this out.

Change argument lists to QBatch with accessors.
Increase default seq_len to 8k.

Jan Wassenberg 6ee628ba38 Further cleanup: separate MatMulEnv arg 
move row_ptrs into MatMulEnv
Consistent arg order: layer, activations, kv_cache, env

Jan Wassenberg 3a266c662c Split gemma-inl into separate source files 
weights, mat: zero-initialize padding, required since the MatMul "avoid B decompress" optimization.
