[SPARK-19085][SQL] cleanup OutputWriterFactory and OutputWriter
## What changes were proposed in this pull request?
`OutputWriterFactory`/`OutputWriter` are internal interfaces and we can
remove some unnecessary APIs:
1. `OutputWriterFactory.newWriter(path: String)`: no one calls it and no
one implements it.
2. `OutputWriter.write(row: Row): Unit`: during execution we only call
`writeInternal`, which is weird as `OutputWriter` is already an internal
interface. We should rename `writeInternal` to `write` and remove `def
write(row: Row): Unit` and it's related converter code. All implementations
should just implement `def write(row: InternalRow): Unit`
## How was this patch tested?
existing tests.
