Fix aggregate function processing to correctly deal with OOMs inside of

sqlite3ParserAddCleanup().
(dbsqlfuzz b2d11ca70e55ee8bde48ae0b53fa3e9355812f95).
Also add improved testing support by causing sqlite3FaultSim(300) to
simulate an OOM inside of sqlite3ParserAddCleanup() and by adding
improved fault-sim support to the CLI.
