x86: Remove generic strncat, strncpy, and stpncpy implementations
These functions all have optimized versions: __strncat_sse2_unaligned, __strncpy_sse2_unaligned, and stpncpy_sse2_unaligned which are faster than their respective generic implementations. Since the sse2 versions can run on baseline x86_64, we should use these as the baseline implementation and can remove the generic implementations. Geometric mean of N=20 runs of the entire benchmark suite on: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz (Tigerlake) __strncat_sse2_unaligned / __strncat_generic: .944 __strncpy_sse2_unaligned / __strncpy_generic: .726 __stpncpy_sse2_unaligned / __stpncpy_generic: .650 Tested build with and without multiarch and full check with multiarch.
