[partition] Migrate the defaultFS type

- remove the m_defaultFSType from PartitionLayout, because it is
  set on construction -- which is too early, before the configuration
  has been read.
- make the default FS explicit in the init() calls which pass in
  a configuration; this needs support in the intermediate
  PartitionCoreModule.
