When the deprecation log is written to within scripting support code like ScriptDocValues, it runs under the reduces privileges of scripts. Sometimes this can trigger log rolling, which then causes uncaught security errors, as was handled in elastic#28485. While doing individual deprecation handling within each deprecation scripting location is possible, there are a growing number of deprecations in scripts. This commit wraps the logging call within the deprecation logger use a doPrivileged block, just was we would within individual logging call sites for scripting utilities.

Do we want this to be wrapped in a doPrivileged block for all calls or just for ones made from scripts?

I think all callers is fine. It is essentially a noop for other callers, since they already run with at least the permissions of the server jar. Scripts are the only place with reduced privileges.
