* for multinode gfx950, extend AR LL128 up to 256MB, extend RS LL128 up to 8MB per rank, extend AG LL up to 64KB per rank
* dont override direct allgather threshold if set to -1
* restore 2-node AR simple at earlier message sizes than higher multi-node AR
* extend range of LL for single-node RS on gfx950
* update algo/proto for multi-node allreduce on gfx942
* set single-node AR on gfx950 to Tree LL for KB message sizes
* decrease threshold for single node Tree for gfx950 AR

* Fail the job if compiler flag HIP_HOST_UNCACHED_MEMORY is not turned on on mi350x
Place the check after initTransportsRank as the GPU arch info in comm->topo->nodes info is populated after that.
* Update src/init.cc to use ERROR instead of WARN

[ROCm/rccl commit: 05f914c997]
* Enhance logging in NCCL initialization
It's convenient to log comms obj and default channels together for debugging
* Add opCount to collDevWork and update increment logic
Added opCount to collDevWork and incremented it when proxyOpQueue is empty (e.g., for intra-node comms)
* Clarify opCount increment logic in enqueue.cc
Updated comment to clarify incrementing opCount for intranode communications.
* Refactor NCCL_INIT logging format
Updated logging format for NCCL_INIT to improve clarity.
