Upgrade abseil-cpp to 20250127 and use @com_google_absl -> @abseil-cpp and com_google_googletest -> @googletest canonical BCR names.

Users still using the old `WORKSPACE` system may need to do the same or use `repo_mapping` on repositories that still use the old names. See Abseil's release notes for details: https://github.com/abseil/abseil-cpp/releases/tag/20250127.
