Summary: This diff adds [ngimel's support for DeepGemm rowwise scaling](https://github.com/ngimel/DeepGEMM/tree/rowwise) to our fbcode copy. It also includes a few deepgemm updates that allow operation on M<128, which is important for any real use case. Performance is increased considerably by the use of rowwise scaling, especially in memory bound cases. Notably, this makes DeepGemm the premier solution for slow accumulation as it now overall outperforms cublas + unfused rowwise scaling. {F1976375307} Differential Revision: D71748927
