Asumu Takikawa 6fe2745f55 Add syntax properties in contract expansion for TR
This establishes a communication channel between the
contract system and TR. TR normally can't track the
relationship between the identifier bound to the transformer
that produces the lifted value expression (which has the
type in the environment) and the lifted expression
itself.

This also adds properties that indicate which parts are
lifted expressions and if a function has an extra negative
party argument.

Finally, the expansion of keyword arguments is modified
slightly to propagate syntax properties on function argument
syntax to the let-bound identifiers that the keyword application
generates.
