Subject: [PATCH] Add runtime deprecation warnings for AbstractMigration and
 AbstractSeed

These classes have had @deprecated docblock annotations since 4.5.0, but
no runtime warnings were emitted. This adds deprecationWarning() calls
so users are notified during execution that they should migrate to
BaseMigration and BaseSeed respectively.
