Room 2.7.0-alpha12

Add the experimental API RoomDatabase.Builder.setInMemoryTrackingMode() to configure whether Room will use an in-memory table or not for invalidation tracking. (I2a9b2, b/185414040) Destructive migrations now drop views to ensure they are recreated, aligning behavior when allowDestructiveMigrationForAllTables is ON (KMP default) with the existing behavior when it's OFF.
