[posix] handle dynamic infra if status (#6186)

Browse Source 
This commit includes below changes:

- handles dynamic infrastructure interface status changes. The Routing
  Manager will be started if the infra interface status turns to be
  RUNNING and a valid link-local address is present. Otherwise, the
  Routing Manager will be stopped.

- changes the default status of the Routing Manager from enabled to
  disabled and it is initially enabled for the posix platform.

- the posix implementation now doesn't require the presence of the
  link-local address at initialization stage. In this case, the
  Routing Manager will not be started before a link-local address is
  added to the infra interface.

- add CI tests for the new behavior.
