92d1dd1c5e Add sealing contracts for row polymorphic types
This enables contract generation in the negative
direction (untyped->typed) for row polymorphic types
(basically mixin types).

Depends on `class-seal` and `class-unseal` in
the racket/class library.

609d6189e9 Improve typecheck for private field initializers
This patch addresses two issues with `typed/racket/class`:

1. For multiple private fields declared with `define-values`, type
information does not propagate from the values produced by the
initialization expression to the declared fields. This breaks soundness
of private fields: A field can be annotated with a type that does not
contain the field's initial value.

This was resolved by keeping a table of temporary bindings introduced in
the expansion of the initializer along with their types. The field
setter's type is then checked against that of the corresponding
temporary.

2. The class body typechecker assumes that the `expr` of
a `define-values` clause will expand to a bare `(values vs ...)`.

This was resolved by generalizing the template for matching an expanded
`define-values` initializer and extracting the type information from the
`expr` instead of each element in `(vs ...)`.

c70910aaa0 Fix type restriction in values->tc-results
Previously the restriction didn't account for traversing
the object type with the given path. This also relies on
the previous commit that adds subtyping on filters.

(because this change seems to introduce filters which
 only differ by an unrolling of a recursive type, but
 the old subtyping only worked for identical types)

8acc86bb9b Add subtyping for types inside filters
This makes a type like

  (-> Any Boolean : #:+ Integer)

a subtype of a type like

  (-> Any Boolean : #:+ Number)

For not filters, the direction is reversed.

33543ce054 Use absent in some row poly class contracts
When exporting row polymorphic functions from TR, just
use absent clauses to ensure that TR won't accidentally
try to add pre-existing fields/methods. No sealing is
needed because the typechecker enforces parameteric use
of the class.
