Support state expiration for with_expression(); rename deferred_expression
The attributeimpl for a deferred_expression does not
support a scalar loader, add new configurability so that
the impl can have this flag turned off. Document
that the with_expression() system currently does not
offer any deferred loading.
To eliminate confusion over "deferred", which refers to
lazy loading of column attributes, and "with_expression",
which refers to an attribute that is explicitly at
query time only, rename deferred_expression to query_expression.
