Add OMATCOPY_CT performance test with RVV optimization

- Created comprehensive performance test for omatcopy_ct function
- Added RVV vectorized implementation with conditional compilation
- Included build script for SG2044 server testing
- Support both scalar and RVV optimized versions
- Added throughput measurement and detailed performance metrics
