[torque]: Class declarations

Class declarations support structured heap data that is a subtype of
HeapObject. Only fields of Object subtypes (both strong and weak)
are currently supported (no scalar fields yet).

With this CL, both the field list macro used with the C++
DEFINE_FIELD_OFFSET_CONSTANTS macro (to make field offset constants) as
well as the Torque "operator '.field'" macros are generated for the
classes declared in Torque. This is a first step to removing the
substantial amount of duplication and boilerplate code
needed to declare heap object classes.

As a proof of concept, and handful of class field definitions,
including those for non trivial classes like JSFunction, have been
moved to Torque.
