If `find_package()` succeeds to find GTest and `INSTALL_DEPENDENCIES`
is set to OFF, `GTEST_BOTH_LIBRARIES` is not set and thus
`rccl-UnitTests` fails with trying to link unkown symbols.
[ROCm/rccl commit: dac0e528a0]
This feature tracks the proxy events and status of each send/recv op. ProxyTrace keeps a fixed number of active ops in host mem and dumps the status of each op when the program crashes or hangs.
[ROCm/rccl commit: 020dcf0a7c]
When the `roc-obj-ls` executable fails, it sometimes does not return. Since the `execute_process` command will wait until the executable finishes, this means that in some cases, the build will hang indefinitely. There is no error message, and no indication that anything is wrong. This commit fixes that by introducing timeouts into the code and better error reporting.

* Add fault injection of starting warps with random variations
This is done by inserting randomly delays after __syncthreads().
The feature can be turned off by FAULT_INJECTION=OFF in cmake.
* Remove manually introduced bug for demo purpose
* Use only one thread per warp for checking wall clock
[ROCm/rccl commit: 90ad586d94]

[ROCm/rccl commit: e9b6bbca8a]
* Changing C-strings to be const.
* Changed variable-length arrays to std::vector to avoid warnings. VLA is a compiler extension.
* Changed `#define` inside functions into `constexpr int` to preserve scoping and avoid macro redefinition warnings.
* Disabled warnings for modifying `CMAKE_CXX_FLAGS` caused by `check_symbol_exists`, which temporarily modifies the flag to do a compile check.
* Fixed VLA in rccl UT.

* cmake: remove mscclpp patch after build is complete
To enable mscclpp in cpx mode, a patch cpx.patch needs to be applied.
This patch can be removed after building is done. This helps with the
build process the following time.
* Use read-based mscclpp allreduce from rccl
MSCCLPP by default uses remote write in the allreduce kernel for
large (> 1MB) messages. This PR adds an allreduce kernel that uses
remote read. It needs the users to use an environment variable
MSCCLPP_READ_ALLRED=1.
[ROCm/rccl commit: 4d68751ce1]
* Added restrictions around calling MSCCL++ collectives (#1281)
* Added restriction to non-zero 32-byte multiple message sizes to MSCCL++ AllGather.
* Renamed and refactored some mscclpp types.
* Only transmit the MSCCL++ unique id for non-split comm init. For splitting comm, it has already been transmitted. Instead, save the MSCCL++ communicator in child communicators when calling `ncclCommSplit`. Only destroy MSCCL++ communicators when no RCCL communicators remain that use it. Also improved trace logging.
* Disable MSCCL++ when using managed memory buffers as it isn't supported.
* Added datatype and op constraints for MSCCL++ AllReduce.
* Added documentation on MSCCL++ restrictions to the README.

* Link to libmscclpp_nccl statically (#1282)
* Switched mscclpp_nccl to static linking. Added a build step to rename the NCCL API functions.
* Undid separation of building libmscclpp_nccl from building librccl with MSCCL++ integration. With a static build, it's either fully enabled or fully disabled.
* `nm` isn't always available in docker containers due to being stripped down. Removed use of `nm` in `cmake` and hard-coded the output into mscclpp_nccl_syms.txt.
* Removed IBVerbs dependency for integrating with MSCCL++ (#1313)
* Renamed `RCCL_ENABLE_MSCCLPP` to `RCCL_MSCCLPP_ENABLE` to conform to MSCCL. Set `RCCL_MSCCLPP_ENABLE` to 1 by default if `ENABLE_MSCCLPP` is defined, or 0 otherwise. Added a log warning if `RCCL_MSCCLPP_ENABLE` is set to 1 but `ENABLE_MSCCLPP` is not defined. (#1294)
* Include mscclpp as a git submodule (#1314)
* Added the desired mscclpp commit as a git submodule.
* Added step to automatically checkout the mscclpp submodule if it isn't already present, in case the user forgot to clone recursively.
* Added instruction to README to clone using --recurse-submodules to get the mscclpp submodule.
* Enabled MSCCL++ feature build.
