Subject: [PATCH] Revisions: Set PHP time limit when generating revision diffs
 vis Ajax.

This aims to avoid hanging PHP processes if a plugin inadvertently attempts to request a large number of revision diffs.

Follow-up to [24520], [24707], [59039].

Props madpeter, lovesoni1999, debarghyabanerjee, pbearne, desrosj, SergeyBiryukov.
Fixes #49291.
