### What changes were proposed in this pull request?
1. Added a checksum mechanism to the shuffle data header.
2. Implemented checksum verification while writing data in the worker.
3. Integrated checksum validation during data reading in
CelebornInputStreamImpl.
4. Added a PushDataHeaderUtils to manage the shuffle data header.
### Why are the changes needed?
Sometimes, the transmitted data may change, leading to errors. Therefore, it
is necessary to add a checksum to detect this exception. I only added a
checksum to the header because I believe that in a production environment, the
data body is mostly compressed, and during compression, a checksum is typically
generated. Therefore, in scenarios where compression is enabled, adding a
checksum to the header is enough.
### Does this PR introduce _any_ user-facing change?
No, this change is compatible.
