Subject: LoongArch:add user_regs_struct and user_fp_struct.
Hi,
elfutils 0.190 references user_regs_struct and user_fp_struct, which
are defined in glibc, but not in musl. So there is a compile error when
compile ruby 3.3.0 in musl. I add these struct in musl loongarch, I also
adjust the ELF_NFPREG according the size of user_fp_struct, and
elf_fpreg_t and elf_fpregset_t definition, which is consistent with glibc.
