[trcrsired]

We do not want any immediate layer for windows.

9x kernel will still use win32

return {fast_io::win32::GetStdHandle(static_cast<std::uint_least32_t>(-10))};

Console handles are accessable via ProcessEnvironment Block NtCurrentPeb()->ProcessParameters->StandardXXX. On x64 PEB is located via gs:[0x60]. I think we can get rid of GetStdHandle by accessing PEB directly.

this change had already been done months ago on my sub rep. I haven't yet merged into this due to more change needs to be done.
