Revert of sandbox: Fix Win64 porting issue by using SIZE_T instead of ULONG (patchset #3 id:40001 of https://codereview.chromium.org/921353002/)

Reason for revert:
Speculative revert after discussion on IRC, this seems pretty unlikely but may have caused the failures at:

Original issue's description:
> sandbox: Fix some nt_internals.h function prototypes for Win64
>
> NtQuerySection should use ULONG instead of SIZE_T as it is dealing with PE section sizes.
>
> NtQueryVirtualMemory should use SIZE_T instead of ULONG as it is dealing with memory sizes.
>
> DynamoRIO, another project that consumes these native APIs, uses the prototypes introduced by this change.
