[I] [C++] Avoid printing very large values [arrow]

[via GitHub]

pitrou opened a new issue, #46403:
URL: https://github.com/apache/arrow/issues/46403

   ### Describe the enhancement requested
   
   This snippet in Python showcases the problem. Arrow will naively attempt to 
print very large items in full when asking to print an array or table:
   ```python
   >>> tab = pa.table({'a': [b"x"*500_000_000]*10})
   >>> tab.nbytes
   5000000040
   >>> tab
   ^C
   ```
   
   
   ### Component(s)
   
   C++
