This adds an env var to enable NCCL health check, which when left unspecified, results in the check not being run. Unit tests that need to test this functionality have the env variable set. Please see internal diff for more details.

Modified loops in files under fbsource/fbcode/caffe2/ from the format
`for(TYPE var=x0;var<x_max;x++)`
to the format
`for(const auto var: irange(xmax))`
This was achieved by running r-barnes's loop upgrader script (D28874212) with some modification to exclude all files under /torch/jit and a number of reversions or unused variable suppression warnings added by hand.

Third try!
Fixes:
- test_nccl_timeout can be flaky because of 1s timeout, bump up the timeout to resolve the flakiness. But in general we should not have been relying on time.sleep for this test, filed https://github.com/pytorch/pytorch/issues/66354 to track that.
- ciflow/all did not actually run tests due to a bug causing multigpu tests to not be run. This has since been fixed.

Initializes dummy NCCL communicators in constructor for a basic health
check that communicators can be initialized prior to launching the first
collective.
After successful init, we immediately use `ncclCommAbort` to destroy these
communicators to ensure they don't interfere with regular communicator creation
during collectives.

KinetoEvent
This PR adds module hierarchy information to events.
What is module hierarchy information attached to events?
During profiling a TorchScript module, when events are added, we ask JIT
what is the module hierarchy associated with the node being
executed. At the time of execution of that node, there might be multiple
frames in the stack of interpreter. For each frame, we find
corresponding node and the corresponding module hierarchy is queried.
Module hierarchy corresponding to the node is associated with node's
InlinedCallStack. InlinedCallStack of node tracks the path via which the
node is inlined. Thus during the inlining process we annotate
module information corresponding to the CallMethod nodes being inlined.
With this PR, chrome trace will contain additional metadata:
"Module Hierarchy". This can look like this:
TOP(ResNet)::forward.SELF(ResNet)::_forward_impl.layer1(Sequential)::forward.0(BasicBlock)::forward.conv1(Conv2d)::forward.SELF(Conv2d)::_conv_forward
It contains module instance, type name and the method name in the
callstack.
