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.
