modernize hybrids and apply typing
Improved the typing support for the :ref:`hybrids_toplevel`
extension, updated all documentation to use ORM Annotated Declarative
mappings, and added a new modifier called :attr:`.hybrid_property.inplace`.
This modifier provides a way to alter the state of a :class:`.hybrid_property`
**in place**, which is essentially what very early versions of hybrids
did, before SQLAlchemy version 1.2.0 :ticket:`3912` changed this to
remove in-place mutation. This in-place mutation is now restored on an
**opt-in** basis to allow a single hybrid to have multiple methods
set up, without the need to name all the methods the same and without the
need to carefully "chain" differently-named methods in order to maintain
the composition. Typing tools such as Mypy and Pyright do not allow
same-named methods on a class, so with this change a succinct method
of setting up hybrids with typing support is restored.
