State trie migration rococo runtime changes. (#6127)

* add state-trie-migration (warn key need to be changed)

* rococo root

* restore master benchs (weights from substrate are used).

* use ord_parameter macro.

* do not upgrade runtime version yet

* apply review changes

* to test ci

* Revert "to test ci"

This reverts commit 5df6c5c74c5d172f254579cbb76caeb44af80ec2.

* test ci

* Revert "test ci"

This reverts commit 0747761644ba566f9756e195e5304758370dc52c.
