[C++] Run-end encoding and decoding: Add support for Decimal32/64 and Float16 #46285
Description
Describe the enhancement requested
Basic run end encoding/decoding support was added in #34382, as part of the larger work to support the REE layout in #34176.
Support for Decimal32, Decimal64, and Float16 (HalfFloat) can now be added to the run_end_encode and run_end_decode kernels. I think both of these types were either in development while REE was being developed or were added after.
