Use GC stack in nested data removal

We should be doing this anyway to prevent stack overflow, but on
master this is important for an additional reason: The temporary
GC buffer provided for get_gc handlers may get reused if the scan
is performed recursively instead of indirected via the GC stack.

This fixes oss-fuzz #23350.
