[WTF] Use `GetCurrentThreadStackLimits` for Windows stack bounds calculation
https://bugs.webkit.org/show_bug.cgi?id=305717
Reviewed by Yusuke Suzuki.
Segmentation Faults caused by preCommitStackMemory were frequently reported in
Bun's Windows port.
To address this, we applied a patch [1] to our fork that uses
GetCurrentThreadStackLimits instead of VirtualQuery,
and released it as Bun 1.3.6. Several days have passed since Bun 1.3.6 was
released, and the same issue has not occurred.
I'm not sure if this issue has been reported in the WebKit Windows Port, but it
should potentially occur there as well.
Therefore, I believe we should also apply the patch we applied to Bun to
upstream.
