Use rb_darray_insert_without_gc for heap_pages darray
rb_darray_insert could trigger a GC, which would cause problems if it
freed pages while a new page was being inserted.
For example, the following script fails:
GC.stress = true
GC.auto_compact = :empty
10.times do
GC.verify_compaction_references(expand_heap: true, toward: :empty)
end
It errors out with:
'GC.verify_compaction_references': malloc: possible integer overflow (8*18446744073709551603) (ArgumentError)
