LUCENE-7323: compound file writing now verifies checksum and segment ID for the
incoming sub-files, to catch hardware issues or filesystem bugs earlier

> For larger segments, there is a non-trivial window, from when IW
> writes sub-files, to when it then builds the CFS, during which the
> files can become corrupted (from external process, bad filesystem,
> hardware, etc.)
> Today we quietly build the CFS even if the sub-files are corrupted,
> but we can easily detect it, letting users catch corruption earlier
> (write time instead of read time).
