erts: Make depth of current_stacktrace configurable
The BIF process_info(Pid, current_stacktrace) truncates the
stacktrace. The old behavior was to truncate long stacktraces to max
8 items. And this was hard coded. Now it is truncated to the value of
system_flag(backtrace_depth) instead. The backtrace_depth defaults to
8, but is configurable.
