Allow multiple C finalizers to be attached to a Weak#
The commit replaces mkWeakForeignEnv# with addCFinalizerToWeak#. This new primop mutates an existing Weak# object and adds a new C finalizer to it. This change removes an invariant in MarkWeak.c, namely that the relative order of Weak# objects in the list needs to be preserved across GC. This makes it easier to split the list into per-generation structures. The patch also removes a race condition between two threads calling finalizeWeak# on the same WEAK object at that same time.
