aarch64: Optimized strlen for strlen_asimd
Optimize the strlen implementation by using vector operations and loop unrolling in main loop.Compared to __strlen_generic,it reduces latency of cases in bench-strlen by 7%~18% when the length of src is greater than 128 bytes, with gains throughout the benchmark. Checked on aarch64-linux-gnu. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
