Jan Wassenberg 301dc8067a Major MatMul update, 1.9-2.3x speedup on Zen4 via bf16 mul 
Supports converting all weight/activation formats to native MulT (bf16/f32)

Also:
- ConstMat/MutableMat for const correctness
- Move RowVectorBatch to allocator.h so it can be used from Matmul
- Add matmul.h so MatMulEnv can be used from Activations
- Remove kMaxThreads, detect from PerClusterPools
- Build fix: -inl.h files must be textual_hdrs, and highway.h should precede -inl.h

```
