Keep the effort in porting BSW to RISC-V
Keep the effort on finalizing the BSW porting from sse to intrinsic RISC-V (adapting Ruben Langarita's porting of sse2sve):
- Finalize the sse2rvv.h library porting.
- Add the appropriate section to write the RISC-V code and replace sve intrinsics with rvv intrinsics on the bandedSWA.cpp.
