[I] [C++] Add new datatypes to the fuzz seed corpus [arrow]

pitrou opened a new issue, #38041:
URL: https://github.com/apache/arrow/issues/38041

   ### Describe the enhancement requested
   
   Part of our seed corpus for IPC fuzzing is generated dynamically here, but it hasn't been updated for the newer datatypes and features:
   https://github.com/apache/arrow/blob/f7530de9fe20f8a3731b465af07a79a56640fe79/cpp/src/arrow/ipc/generate_fuzz_corpus.cc#L68
   
   We should add the newer datatypes (run-end encoding, list view, string view) and ideally also new IPC features such as optional buffer compression (perhaps generate both compressed and uncompressed files).
   
   ### Component(s)
   
   C++, Continuous Integration

   @zeroshade Can we prioritize this for 0.15.0? This a rather small task and is important to ensure robustness of the newly added data type implementations.

   Note that you can check your work by running this nightly build, or reproducing its steps locally:

   For example you can see the dynamic generation occurring here:

   @felipecrv Are you still interested in this? This is really something that we should do, otherwise we may be missing out on potential reliability issues.

   With all the reviews and Flight/SQL/REST work, I don't have time to take another workstream :/

   I'm assigning myself. I will at least get this started.
