runtime/traceback: support tracking goroutine ancestor tracebacks with GODEBUG="tracebackancestors=N"
Currently, collecting a stack trace via runtime.Stack captures the stack for the
immediately running goroutines. This change extends those tracebacks to include
the tracebacks of their ancestors. This is done with a low memory cost and only
utilized when debug option tracebackancestors is set to a value greater than 0.
Resolves #22289
