* fixes for CVE-2024-8775
* propagate truthy `_ansible_no_log` in action result (previously superseded by task-calculated value)
* always mask entire `include_vars` action result if any file loaded had a false `show_content` flag (previously used only the flag value from the last file loaded)
* update no_log tests for CVE-2024-8775
* include validation of _ansible_no_log preservation when set by actions
* replace static values with dynamic for increased robustness to logging/display/callback changes (but still using grep counts :( )
* changelog
* use ternary, coerce to bool explicitly
(cherry picked from commit c9ac477e53)
