LOG: [LoongArch][Clang] Make the parameters and return value of {x,}vorn.v builti ns `unsigned char` vectors (#114514)

All other bitwise vector builtins use `unsigned char` vector operands,
so it does not make too much sense to use `signed char` for the orn
operation alone.
    
The same change has been also proposed for GCC:
https://gcc.gnu.org/pipermail/gcc-patches/2024-October/667065.html.

Depends on #114513.
