### What changes were proposed in this pull request?
At a new parameter, allow CelebornShuffleReader to decompress data on demand
### Why are the changes needed?
In the current scenario of Gluten Fallback, a stage can have both Native and
Java shuffles simultaneously. In
[CELEBORN-1625](https://issues.apache.org/jira/browse/CELEBORN-1625), we
introduced a new parameter to conditionally skip compression. Alongside this,
we should add a corresponding parameter to ensure that the Celeborn shuffle
reader does not decompress data when compression is skipped at pushOrMergeData.
### Does this PR introduce _any_ user-facing change?
