Introduce multi-rank support per device.
...
This is a single commit of the source code changes required to
introduce support for multiple ranks per device.
A new interface (ncclCommRankInitMulti) has to be used to make use of
this new feature.

fix cmake logic to handle old and new include dirs

fix cmake logic to handle old and new include dirs
...
Starting from rocm 5.2 there is a reorganization of the
include directories. This pr allows to compile
rccl on both the old and the new directory layout.
This solution is using find_package() for identifying correct
settings for rocm_smi starting from rocm-5.2, and the original (manual)
settings for all previous releases.
Tested with rocm-5.2, 5.1.1, 5.0.2, and 4.5.2.
