update for riscv V extension 1.0 and arbitrary shape gemm kernels 

* all modules compile with latest tools and vector extension version
* easily reconfigure for different architecture preferences
* reduce LMUL to avoid register spills (note LMUL=8 uses a quarter of the register bank per variable!)
* multiple test fixes - corner cases (zero/negative inputs), nrm2 numeric stability
* added vectorised implementations for sum/zsum
