feat: allow changing L1 synced height via admin RPC/CLI (#1044)

* feat: allow changing L1 synced height via RPC/CLI

* chore: auto version bump [bot]

* fix typos

* add height validity check

* change implementation

* moved hotfix apis from ScrollAPI to PrivateAdminAPI

* change namespace from scroll to admin

* fix bugs

* add locks

* add a lock to protect latestProcessedBlock and db state

* revert some changes

* remove lock and use atomic in latestProcessedBlock

* fix CI

* tweak

* use cas in updating latestProcessedBlock

* renaming

* also update sync height in error paths

* fix a bug

* use mutex lock
