traced_perf: feed samples through libunwindstack

Added per-DS bookkeeping queues with the same structure of periodic tick
tasks that process a queue of unwound samples.

All the per-instance maps have the same lifetime at the moment, but I'm
keeping them separate as the ownership will become more segmented once the
unwinding is put onto a separate thread (and ProcDescriptors will be
sharded, so keeping the current name for now).
