[roll] Roll fuchsia [profiler] Add unwinding mechanism to stack sampler

The profiler now performs a full stack unwind instead of just capturing
raw stack memory. This change enables the collection of Program Counter
(PC) sequences for each sampled thread, providing structured call
stacks.

Key improvements include:
* Introduced a BufferedStackMemory class to manage memory reads and
  dynamically capture stack chunks during the unwinding process.
* Implemented a mechanism to capture restricted states,
  enabling the unwinder to do the Starnix-to-Android transition.
