CORDA-3720 Extract locking of InnerState out of SMM (#6289)
The state machines state is held within `InnerState` which lived inside
the SMM. `InnerState` has been extracted out of the SMM to allow the SMM
to be refactored in the future. Smaller classes can now be made that
focus on a single goal as the locking of the state can be accessed from
external classes. To achieve this, pass the `InnerState` into the class
and request a lock if needed.

The locking of `InnerState` has been made a property of the `InnerState`
itself. It has a `lock` field that allows locks to be taken out when
needed.

An inline `withLock` function has been added to tidy up the code and not
harm performance.

Some classes have been made internal to prevent invalid usage of purely
node internal classes.

As part of this change, flow timeouts have been extracted out into
`FlowTimeoutScheduler`.
