/**
 * Store #PyObject data for a dynamically defined property.
 * Currently this is only used to store call-back functions.
 * Properties that don't use custom callbacks won't allocate this struct.
 *
 * Memory/Reference Management
 * ---------------------------
 *
 * This struct adds/removes the user-count of each #PyObject it references,
 * it's needed in case the function is removed from the class (unlikely but possible),
 * also when an annotation evaluates to a `lambda` with Python 3.10 and newer e.g: #86332.
 *
 * Pointers to this struct are held in:
 *
 * - #PropertyRNA.py_data (owns the memory).
 *   Freed when the RNA property is freed.
 *
 * - #g_bpy_prop_store_list (borrows the memory)
 *   Having a global list means the users can be visited by the GC and cleared on exit.
 *
 *   This list can't be used for freeing as #BPyPropStore doesn't hold a #PropertyRNA back-pointer,
 *   (while it could be supported it would only complicate things).
 *
 *   All RNA properties are freed after Python has been shut-down.
 *   At that point Python user counts can't be touched and must have already been dealt with.
 *
 * Decrementing users is handled by:
 *
 * - #bpy_prop_py_data_remove manages decrementing at run-time (when a property is removed),
 *
 * - #BPY_rna_props_clear_all does this on exit for all dynamic properties.
