aarch64: Optimized implementation of strnlen
Optimize the strlen implementation by using vector operations and loop unrooling in main loop. Compared to aarch64/strnlen.S, it reduces latency of cases in bench-strnlen by 11%~24% when the length of src is greater than 64 bytes, with gains throughout the benchmark. Checked on aarch64-linux-gnu. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
