… directly instead of reflectively (#3686)

This pull request fixes issue #3686 by having org.apache.logging.log4j.util.Base64Util invoke java.util.Base64 directly instead of reflectively. This avoids the need to use javax.xml.bind.DataTypeConverter as a fallback, which has been problematic because it is not Jakarta EE9 compliant.

@ppkarwasz, I'm afraid that by squashing my commits, the signature disappeared ... Should I create a new PR?

In general we prefer to use the same PR. Missing signatures can be corrected via a forced push that replaces all the commits:

git rebase --force-rebase --gpg-sign origin/2.x
git push --force
