Add runtime option to enable/disable lcnt stats

Add erts_debug:lock_counters({copy_save, bool()}). This option
enables or disables statistics saving for destroyed processes and
ets-tables. Enabling this might consume a lot of memory.

Add id-numbering for lock classes which is otherwise undefined.
