Original change's description:
> [utils] Make HeapArray aligned to max_align_t for byte types.
>
> Previously HeapArray wouldn't pass an alignment to operator new[] which
> would result in an implementation defined alignment used. Instead detect
> the case of byte-type arrays and use max_align_t for alignment.
>
>  - Add DeleteAllocationFromHeapArray to ensure deletions handle the MSVC
>    workaround and use that method everywhere delete[] was used directly.
>  - Remove the now unused MoveToRawPtr.
>  - Modify the alignment tests to stress test that path a bit more.
