[SPARK-15657][SQL] RowEncoder should validate the data type of input object
## What changes were proposed in this pull request?
This PR improves the error handling of `RowEncoder`. When we create a
`RowEncoder` with a given schema, we should validate the data type of input
object. e.g. we should throw an exception when a field is boolean but is
declared as a string column.
This PR also removes the support to use `Product` as a valid external type
of struct type. This support is added at
https://github.com/apache/spark/pull/9712, but is incomplete, e.g. nested
product, product in array are both not working. However, we never officially
support this feature and I think it's ok to ban it.
## How was this patch tested?
new tests in `RowEncoderSuite`.
