* Detect if HSA_NO_SCRATCH_RECLAIM is set after initEnv()
For rocm older than 6.4, we need to set HSA_NO_SCRATCH_RECLAIM=1 to use LL128 protocol.
This Env is set outside of RCCL, add the logging to detect whether its set during runtime.
* check hip runtime ver via hipRuntimeGetVersion
* move the detection to ncclinit func
* correct rocm version integer
* update warning message
* avoid unnecessary info msg on hsa_no_scratch_reclaim detection
* Fix when more than 64 channels are used for multi-collective group calls
* Update CHANGELOG.md

* Cleanup
* Use DMABuff or Peermem as needed
* Using user input for ibDmaBufSupportInitOnce
* Revert all changes to rocmwrap.cc
* Revert all changes to rocmwrap.cc
* Changing to func definition braces
* Reverting line removal in utils.h

* mscclpp patch apply clip patch and set allreduce8 blocks from 512 to 1024
* add compilation flag for enabling/disabling clipping in mscclpp
* change flag name for consistency, set flag to OFF
* add compilation flag in rccl for enabling clipping in mscclpp
* set 1024 threads for mscclpp allreduce8 only for bfloat16
* fix improper description for ENABLE_MSCCLPP_CLIP flag
* Revert "Merge branch 'clip-patch' of https://github.com/isaki001/rccl into clip-patch"
This reverts commit 6e31857a9db98314b8a748eb024f2c3699ebe2d5, reversing
