LoongArch: Add ifunc support for strnlen{aligned, lsx, lasx}
Based on the glibc microbenchmark, strnlen-aligned implementation could reduce the runtime more than 10%, strnlen-lsx implementation could reduce the runtime about 50%-78%, strnlen-lasx implementation could reduce the runtime about 50%-88%.
