Modernize internal reflection

- Deprecated remaining engine-level introspection and utility methods
including :meth:`.Engine.run_callable`, :meth:`.Engine.transaction`,
:meth:`.Engine.table_names`, :meth:`.Engine.has_table`.   The utility
methods are superseded by modern context-manager patterns, and the table
introspection tasks are suited by the :class:`.Inspector` object.

- The internal dialect method ``Dialect.reflecttable`` has been removed.  A
review of third party dialects has not found any making use of this method,
as it was already documented as one that should not be used by external
dialects.  Additionally, the private ``Engine._run_visitor`` method
is also removed.

- The long-deprecated ``Inspector.get_table_names.order_by`` parameter has
been removed.

- The :paramref:`.Table.autoload_with` parameter now accepts an :class:`.Inspector` object
directly, as well as any :class:`.Engine` or :class:`.Connection` as was the case before.

Fixes: #4755
