configure: Check that sqlite3 has sqlite3_auto_extension() enabled
Only do this if we need to load the FTS5 module, sqlite3 might have been compiled with SQLITE_OMIT_LOAD_EXTENSION, which will make things go very wrong (poking NULL vfuncs in a 0'ed out sqlite3_api_routines) at runtime. This facility must be enabled if we need to load our FTS module, so bail out at configure time if it's not there.
