Subject: [PATCH] [MDEV-28992] Push down TIMESTAMP_DIFF in spider

This changes so that TIMESTAMP_DIFF function in a query is pushed down and works natively in Spider.
Instead of directly accessing item's member, now we can rely on a public accessor method to make it work.
Unit tests are added under spider.pushdown_timestamp_diff.
