runtime: make zeroing of large objects containing pointers preemptible This change makes it possible for the runtime to preempt the zeroing of large objects that contain pointers. It turns out this is fairly straightforward with allocation headers, since we can just temporarily tell the GC that there's nothing to scan for a large object with a single pointer write (as opposed to trying to zero a whole bunch of bits, as we would've had to do once upon a time). Fixes #31222.
