LOG: [LoongArch][Clang] Make the parameters and return value of {x,}vshuf.b builtins `signed char` vectors (#114512)

The lsxintrin.h and and lasxintrin.h headers uses `signed char` vectors
instead of `unsigned char` vectors.  GCC also uses `signed char` for
them, so align their definition with the headers and GCC.

Depends on #114511.  Part of #110834 fix.
