Add aws ofi rccl (#32773)

* Added a package for the aws-ofi-rccl plug-in from the ROCm software
stack.  It allows RCCL to use the libfabric communication library.

Added support for using libfabric in Aluminum.

* Updated the run environment so that the plugin would get loaded.

* Added support for setting up the the LD_LIBRARY_PATH for dependent packages.

* Added package for RCCL tests to assess the impact of OFI libfabric RCCL plug-in.
