Jun Wu b9e3046a8d indexedlog: add Checksum entry to Index
Summary:
To solve the soundness issue of ChecksumTable raised by the last diff.
I plan to move Checksum logic to Index. This has multiple benefits:
- Solve the soundness issue of ChecksumTable.
- Indexedlog no longer writes the ".sum" files. `atomic_write` can be quite
  slow (tens of milliseconds) on Windows. So this should help perf - with
  many indexes, it can save hundreds of milliseconds on Windows per
  indexedlog sync.

This diff adds the definition and serialization of the new Checksum entry.
The index format is not updated yet.
