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.
