xplist: Convert nested {CF$UID:<int>} dicts to PLIST_UID safely

Convert single-entry { "CF$UID" : <integer> } dictionaries to PLIST_UID
nodes when closing a dict in the XML parser.

Refactor node cleanup logic:
- Split plist_free_data() into internal _plist_free_data()
- Introduce plist_free_children() to release child nodes separately
- Update plist_set_element_val() to free children before changing
  container node types
- Ensure PLIST_DICT hashtables do not free values (assert + force
  free_func = NULL)

This avoids in-place container mutation issues and ensures child
nodes and container metadata are released correctly before
changing node type.
