[SPARK-15632][SQL] Typed Filter should NOT change the Dataset schema

## What changes were proposed in this pull request?

This PR makes sure the typed Filter doesn't change the Dataset schema.

**Before the change:**

```
scala> val df = spark.range(0,9)
scala> df.schema
res12: org.apache.spark.sql.types.StructType = 
StructType(StructField(id,LongType,false))
scala> val afterFilter = df.filter(_=>true)
scala> afterFilter.schema   // !!! schema is CHANGED!!! Column name is changed 
from id to value, nullable is changed from false to true.
res13: org.apache.spark.sql.types.StructType = 
StructType(StructField(value,LongType,true))

```

SerializeFromObject and DeserializeToObject are inserted to wrap the Filter, 
and these two can possibly change the schema of Dataset.

**After the change:**

```
scala> afterFilter.schema   // schema is NOT changed.
res47: org.apache.spark.sql.types.StructType = 
StructType(StructField(id,LongType,false))
```

## How was this patch tested?

Unit test.

Closes #13529 from clockfly/spark-15632.
