Introduce `verify-ldso-abi.sh` script and architecture-specific baseline files to the build. This new verification step is integrated into the `%check` phase of the glibc build process. It uses `gdb` to dump the internal ABI layout of critical dynamic linker data structures (`_rtld_global_ro`, `_rtld_global`, `struct link_map`, `struct pthread`) and compares them against a predefined baseline. This ensures that unintentional ABI breaks in `ld.so` are detected early, maintaining stability for internal glibc components. The script also supports generating new baselines when changes are intentional. Resolves: RHEL-72564
