mnesia: let loader check if tablelock is needed
move_table_copy needs the lock that was set previously in del_table_copy.
This doesn't work on old nodes, so bump protocol version and check it.
Remove old protocol conversion code, which have been around since OTP-R15.
Checking if lock is needed requires rpc communication via mnesia_gvar
ets table to be backwards compatible.
