Loongarch: Add ifunc support for memcpy{aligned, unaligned, lsx, lasx} and memmove{aligned, unaligned, lsx, lasx}
These implementations improve the time to copy data in the glibc microbenchmark as below: memcpy-lasx reduces the runtime about 8%-76% memcpy-lsx reduces the runtime about 8%-72% memcpy-unaligned reduces the runtime of unaligned data copying up to 40% memcpy-aligned reduece the runtime of unaligned data copying up to 25% memmove-lasx reduces the runtime about 20%-73% memmove-lsx reduces the runtime about 50% memmove-unaligned reduces the runtime of unaligned data moving up to 40% memmove-aligned reduces the runtime of unaligned data moving up to 25%
