  Log Message:
  -----------
  [llvm-objdump] Rework .gnu.version_d dumping

and fix crash when vd_aux is invalid (#86611).

vd_version, vd_flags, vd_ndx, and vd_cnt in Elf{32,64}_Verdef are
16-bit. Change VerDef to use uint16_t instead.

vda_name specifies a NUL-terminated string. Update getVersionDefinitions
to remove some `.c_str()`.
