Integrate MSCCL++ with torch
Introduce `NCCL audit shim library`, use can use following commands to
launch torch library. Also avoid break build pipeline in the CPU machine
```bash
export LD_AUDIT=$MSCCLPP_INSTALL_DIR/libmscclpp_audit_nccl.so
export LD_LIBRARY_PATH=$MSCCLPP_INSTALL_DIR:$LD_LIBRARY_PATH
torchrun --nnodes=1 --nproc_per_node=8 your_script.py
```
For push function, we only need to make sure the instruction `st.global`
will be executed after the while loop. Since there is a Write-After-Read
hazard for `trigger.fst` (Check `this->triggers[curFifoHead % size].fst
!= 0` first then write value to `triggers[curFifoHead % size]`), we can
expect the compiler and hardware can handle this situation correctly.
Remove the `release.sys` there.
BTW, `st.global.release.sys.v2.u64` will cause perf regression issue.
Previous we use `st.global.release.cta.v2.u64`, but seems not necessary.
