PySide6/support: Add auto_property_helper.py

- Borrowed from the original implementaton in QtBridge
- A lot of these helpers are introspection like inspecting python
  classes, generating getters/setters needed for
  @auto_properties, finding out the return annotation of property
  getters, and they done in pure python code. This could also be
  done in CPython but does not really offer any significant performance
  advantages. The overall module implementation is in CPython because
  we refer to a lot of PySide:: namespace internal API.
- Loaded lazily by the C++ @auto_properties decorator via
  PyImport_ImportModule
- AST visitor for @auto_properties support
- Builds Property + Signal pairs for __init__ attributes, with
  getters/setters that skip the first (silent) __init__ write
- Converts native @property → Property, reusing the user's getter/setter
  but adding change notification
- Wires observers (@watch, @effect, @computed) onto existing Property
  setters without double-emitting the notify signal
- Materialises @computed as read-only Property objects with lazy
  first-access caching. Dependency changes trigger eager re-evaluation
  via _recompute.
- Maps Python types to Qt meta types

libpyside: Add MetaObjectBuilder::reparseType()

- Clears the existing QMetaObjectBuilder and re-runs parsePythonType()
  on the given Python type
- Needed by @auto_properties, which adds Signal and Property objects to
  the class dict after the initial QMetaObject has already been built
  by initQObjectSubType()

libpysideqml: Add @auto_properties decorator

- @auto_properties CPython API decorator for auto-generating Qt
  properties from Python attributes
- This now builds PySide6 Property objects with notify signals
  and rebuilds the QMetaObject via reparseType()
- Calls 'augment_class()' Python function which is responsible
  for inspecting the class, creating PySide properties and triggering
  the observers on property changes
- Export retrieveTypeUserData() from libpyside so libpysideqml can
  rebuild the QMetaObject

Object list model example: Use @auto_properties and @watch

- Use @auto_properties so plain self.name/self.color assignments become
  PySide.QtCore.Property with notify signals, removing the boilerplate
- Add @watch("color") to react to color changes with old/new values
- Add a TapHandler to the delegate so clicking a row recolors it,
  triggering the @watch callback on a real QML write
