Why this is good for CI: we don't really build with Eigen ever and gitlab can be down when github is up, which causes spurious CI failures in the past, for example.

* The `rocm-core` CMake package only started appearing in ROCm 6.4, so rework the version probing to work if it is not present. Also collapses the unneeded operating system conditioning in favor of feature probing.
* Make `hipsparselt` optional: it only started appearing in ROCm 6.4 and it is not in all recent distribution channels yet.

This enables Gloo CUDA when used with a backend that supports GPUDirect which currently is only the IBVERBS backend.
This requires some changes to Gloo which are in https://github.com/pytorch/gloo/pull/441
Since we're now depending on gloo_cuda we need to split ProcessGroupGloo into two pieces, one with the CPU bits (libtorch_cpu) and one with CUDA kernels in libtorch_cuda. This unfortunately requires some major refactoring as some CPU code is shared across both.
The gloo submodule is updated to depend on the new Gloo changes
Test plan:

In this approach, we are catching any lane within a wave that is doing fastatomics to the same destination address and computing the sum on the CU. This is leading to 3x improvement in scatter_add performance and 2x improvement in index_select.

Summary:
Profiler side of memory snapshot.
1. Add API to actually do snapshot when client interface is called
2. Add ifdefs to builds so that kineto hooks snapshot correctly.
Design Philosophy: There is one interesting part of this implementation and it is during export. For export we are callign the python impl of the export rather than CPP even though we are already in CPP. This is because it is better to simply have one path of export rather than 2. Personally, I want there to be parity between auto-trace and on-demand so it if we can limit the side paths then we will have an easier time maintaining this relationship

- Solves a problem related to .hip source files being ignored by the build system when HIP language is not enabled in CMake.
- Also ensures that the test executables link to an appropriate CRT Runtime Library and hence have access to all the necessary symbols. Previously, there were many problems related to linkage errors.
- Moves part of Linux-related hipBLASLt changes in `LoadHIP.cmake` under the UNIX conditional branch, as these aren't supported on Windows yet.

The PR enables CUPTI on Windows and enables unit tests to check CUDA profiling events.
Additionally, the changes can be verified using the following script:
```
import torch
from torch.profiler import profile, ProfilerActivity
def check_cupti_enabled():
# Check if CUDA is available
if not torch.cuda.is_available():
print("CUDA is not available on this system.")
return False
# Create a simple CUDA tensor
x = torch.randn(1000, 1000, device="cuda")
y = torch.randn(1000, 1000, device="cuda")
try:
# Use PyTorch profiler to perform a basic check
with profile(activities=[ProfilerActivity.CUDA]) as prof:
z = x @ y # Simple CUDA operation
# Print profiling results
print("CUPTI is enabled and profiling works.")
print(prof.key_averages().table(sort_by="cuda_time_total", row_limit=10))
return True
except RuntimeError as e:
# If profiling fails, CUPTI is likely not set up correctly
print("Error: CUPTI might not be enabled or accessible.")
print(f"Details: {e}")
return False
if __name__ == "__main__":
if check_cupti_enabled():
print("CUPTI is properly configured in PyTorch.")
else:
print("CUPTI is not configured correctly. Check your CUDA installation.")
```
Sample output:
```

I experienced an error while doing a DEBUG build of pytorch on rocm:
```
additional relocation overflows omitted from the output
/usr/bin/ld: failed to convert GOTPCREL relocation; relink with --no-relax
```
Based on discussions on similar issue #138427, I fixed it after adding the `--offload-compress` to the HIP_HIPCC_FLAGS to successfully build DEBUG mode on my node.
Further updated the PR to enable the flag for non-DEBUG builds as well due to the size reduction.
