sqlite3: updated to 3.39.4

Changes in version 3.39.4 (2022-09-29):

Fix the build on Windows so that it works with -DSQLITE_OMIT_AUTOINIT
Fix a long-standing problem in the btree balancer that might, in rare cases, cause database corruption if the application uses an application-defined page cache.
Enhance SQLITE_DBCONFIG_DEFENSIVE so that it disallows CREATE TRIGGER statements if one or more of the statements in the body of the trigger write into shadow tables.
Fix a possible integer overflow in the size computation for a memory allocation in FTS3.
Fix a misuse of the sqlite3_set_auxdata() interface in the ICU Extension.
