NVIDIA GPU profiling support

[elgalu]

Feature Request

Support for GPU profiling similar to what's currently being offered for CPU.

Alternative solutions

1. Sentry's (OSS) OpenTelemetry Collector collects GPU metrics
2. Framework-specific like PyTorch Profiler or TensorFlow Profiler that could be incorporated into this product to provide it as a service out of the box.

Is there a use case or business reason for this request?

The CPU market is growing at a compound annual growth rate (CAGR) of 4.36% while the GPU market grows at a CAGR of 33.4%. Also NVIDIA has the biggest market share at 80%.

I love this idea! No clue if we can use eBPF for this, but pprof is a generic format, so as long as we can get it into that format we can make it work!
