CI: Retry build up to three times in KMP workflow

This commit updates the `kmp.yml` GitHub Actions workflow to add a retry mechanism for the build step.

The build process will now be attempted up to three times upon failure. This is intended to mitigate intermittent build issues. The step names have been updated to reflect the attempt number (e.g., "Build (1st attempt)").
