Mark data lifecycle APIs as stable

[pquentin]

As noticed in #3019, but extracting it into its own pull request is easier until the IP location APIs are merged. This also include an unrelated fix to the same APIs that I submitted to Elasticsearch: elastic/elasticsearch#116292

The backport to 8.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-8.x 8.x
# Navigate to the new working tree
cd .worktrees/backport-8.x
# Create a new branch
git switch --create backport-3109-to-8.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 17693a6ccd679cb943c952838a700c673b13b9ad
# Push it to GitHub
git push --set-upstream origin backport-3109-to-8.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.x

Then, create a pull request where the base branch is 8.x and the compare/head branch is backport-3109-to-8.x.
