sqlite: Remove custom PRAGMA auto_vacuum_slack_pages. SQLite patch 0007-Allow-auto-vacuum-to-work-with-chunks.patch introduces a PRAGMA that is not used outside of tests. The PRAGMA was added for an experiment that was discontinued, referenced on the bug above. This CL removes the patch and the associated tests, reducing the total amount of patches we carry on top of SQLite. No functional changes are expected, because the patch is inert in production. Specifically, the newly introduced autoVacuumSlack member of the BtShared structure is zero-initialized by default, and can only be changed by issuing the auto_vacuum_slack_pages PRAGMA. The new btree code is gated by an if (... && pBt->autoVacuumSlack). The PRAGMA is not used outside of testing.
