[JENKINS-73158] avoid jumping layout due to tooltips

[mawinter69]

The fix for JENKINS-72744 made the tooltip get appended to the parent element. But this can also cause troubles in some cases. To avoid this one can now decide whether the tooltip should be appended to the body (the default) or to the parent.
Adjust all locations where a tooltip is displayed inside a widget to append it to the parent. This works well with those tooltips and avoids a jumping layout in the custom-folder-icon and potentially other places.

See JENKINS-73158.

Testing done

Manual testing that in widgets the tooltips are properly removed while with custom-folder-icon plugin, the layout stays stable.

Submitter checklist

Beta Give feedback

1. The Jira issue, if it exists, is well-described.
2. The changelog entries and upgrade guidelines are appropriate for the audience affected by the change (users or developers, depending on the change) and are in the imperative mood (see examples). Fill in the Proposed upgrade guidelines section only if there are breaking changes or changes that may require extra steps from users during upgrade.
3. There is automated testing or an explanation as to why this change has no tests.
4. New public classes, fields, and methods are annotated with @Restricted or have @since TODO Javadocs, as appropriate.
5. New deprecations are annotated with @Deprecated(since = "TODO") or @Deprecated(forRemoval = true, since = "TODO"), if applicable.
6. New or substantially changed JavaScript is not defined inline and does not call eval to ease future introduction of Content Security Policy (CSP) directives (see documentation).
7. For dependency updates, there are links to external changelogs and, if possible, full differentials.
8. For new APIs and extension points, there is a link to at least one consumer.

3. Changelog entries in the pull request title and/or Proposed changelog entries are accurate, human-readable, and in the imperative mood.
4. Proper changelog labels are set so that the changelog can be generated automatically.
5. If the change needs additional upgrade steps from users, the upgrade-guide-needed label is set and there is a Proposed upgrade guidelines section in the pull request title (see example).
6. If it would make sense to backport the change to LTS, a Jira issue must exist, be a Bug or Improvement, and be labeled as lts-candidate to be considered (see query).

Looks good in my interactive testing both with custom folder icon and without.
