Wrap checked exceptions in painless.DefBootstrap

[andrross]

A behavior change in JDK-25 means that ClassValue.getFromHashMap will now wrap any checked exceptions with java.lang.Error. The fix is to wrap checked exceptions in ClassValue.computeValue with a specific RuntimeException wrapper, and then unwrap it later when handling.

The backport to 2.19 failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.19 2.19
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.19
# Create a new branch
git switch --create backport/backport-19706-to-2.19
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 8feb6e14ffbcf75c10eb8f90158fa27299a7b14c
# Push it to GitHub
git push --set-upstream origin backport/backport-19706-to-2.19
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.19

Then, create a pull request where the base branch is 2.19 and the compare/head branch is backport/backport-19706-to-2.19.
