RFR: 8299915: Remove ArrayAllocatorMallocLimit and associated code

[Afshin Zafari]

1. `ArrayAllocatorMallocLimit` is removed. The test cases that tested it also are removed.
2. `AllocArrayAllocator` instances are replaced with `MallocArrayAllocator`.
3. The signature of `CHeapBitMap::free(ptr, size)` is kept as it is, since it is called in this way from `GrowableBitMap<T>::resize`, where `T` can be also `ArenaBitMap` and `ResourceBitMap`. However, it uses `MallocArrayAllocator::free(ptr)` and ignores the `size`:
```C++
void CHeapBitMap::free(bm_word_t* map, idx_t size_in_words) const { 
 MallocArrayAllocator<bm_word_t>::free(map);
}

### Test
tiers1-4 passed on all platforms.
