Summary

Add RISC-V Vector optimized distance operators for both single and batch computation paths.

This PR introduces RVV implementations for supported distance operators and wires them into the existing CPU feature dispatch flow. Existing x86 SIMD and fallback implementations remain unchanged.

Changes

  • Add RVV non-batch distance operators
  • Add RVV batch distance operators
