Remove some iOS #ifdefs by adding SQLiteDatabaseTracker to all the builds

Remove some iOS #ifdefs by adding SQLiteDatabaseTracker to all the builds
https://bugs.webkit.org/show_bug.cgi?id=127632

Reviewed by Darin Adler.

Move the SQLiteDatabaseTracker and client from platform/sql/ios to platform/sql,
as there is nothing iOS specific about it. Then, un-#ifdef all its uses. For
ports that don't setup a client, this has no change in behavior.
