[SPARK-8961] [SQL] Makes BaseWriterContainer.outputWriterForRow accepts
InternalRow instead of Row
This is a follow-up of [SPARK-8888] [1], which also aims to optimize
writing dynamic partitions.
Three more changes can be made here:
1. Using `InternalRow` instead of `Row` in
`BaseWriterContainer.outputWriterForRow`
2. Using `Cast` expressions to convert partition columns to strings, so
that we can leverage code generation.
3. Replacing the FP-style `zip` and `map` calls with a faster imperative
`while` loop.
