[roll] Roll fuchsia [32bit][profiler] Implement Skeleton for Stack Sampling

This change introduces the `StackSampler` class, intended to handle
DWARF-based stack sampling. It updates `ProfilerControllerImpl` to
inspect the sampling configuration's callgraph strategy.

If `CallgraphStrategy::kDwarf` is selected, the controller now
instantiates a `StackSampler`. The current implementation of
`StackSampler::Start` returns `ZX_ERR_NOT_SUPPORTED` as a placeholder.

The existing logic for frame pointer sampling is preserved and moved
under the `CallgraphStrategy::kFramePointer` case.
