[Vishwanatha-HD]

Describe the enhancement requested

This is the sub-issue opened which is part of #48151.

This enhancement is opened to track the fixes for "Column Reader" & "Column Writer" logic to enable support on Big-endian (s390x) platforms.
Column Readers & Writers form main part of many parquet & arrow-parquet testcases.

The fix has been tested on s390x platforms and it works fine. The fix has also been tested on x86 arch, just to make sure its no new regression introduced with this fix.
