[Sema] Use type refinement context of storage as parent for accessor functions.

This commit changes building of type refinement contexts for accessor functions
to use the type refinement context of its associated storage as a parent
rather than its lexically-enclosing context. With this change, we now
associate new child contexts inside property accessors with the TRC of the
property rather than the TRC of the container of the anonymous function created
for the accessor. This commit also adds a dump() debug method to
TypeRefinementContext.
