Ensure .engine is part of Connectable interface, implement as descriptor
Fixed bug where using reflection function such as :meth:`.MetaData.reflect`
with an :class:`.Engine` object that had execution options applied to it
would fail, as the resulting :class:`.OptionEngine` proxy object failed to
include a ``.engine`` attribute used within the reflection routines.
Fixes: #4754
