erts: Replace meta_pid_to{_fixed}_tab with linked lists
from process psd through all owned/fixed tables. As meta_pid_to{_fixed}_tab maps to slot in meta_main_tab which is planned for destruction. In this commit we no longer seize table lock while freeing the table (free_table_cont) as it's not needed and makes the code a bit simpler. Any concurrent operation on the table will only access lock, owner and status and then bail out.
