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.
