Wenchen Fan 49fb237081 [SPARK-14270][SQL] whole stage codegen support for typed filter ... ## What changes were proposed in this pull request? We implement typed filter by `MapPartitions`, which doesn't work well with whole stage codegen. This PR use `Filter` to implement typed filter and we can get the whole stage codegen support for free. This PR also introduced `DeserializeToObject` and `SerializeFromObject`, to seperate serialization logic from object operator, so that it's eaiser to write optimization rules for adjacent object operators. ## How was this patch tested? existing tests.
