Revert of Precisely determine Windows thread stack size. (patchset #1 id:1 of https://codereview.chromium.org/1409243011/ )

Reason for revert:

Original issue's description:
> Precisely determine Windows thread stack size.
>
> The Thread Information Block (TIB)'s StackLimit records the end of
> the committed area of the thread's stack reservation, hence it cannot be
> used to determine the overall size of the reserved stack. Switch to
> a VirtualQuery() lookup instead, but taking care to cache the result per
> thread so as to avoid calling overhead.
