Function debug_here_win_impl 

pub fn debug_here_win_impl()

Pop open a debugger on windows.

Windows has native just-in-time debugging capabilities via the debugapi winapi module, so we use that instead of manually popping open a termianl and launching the debugger in that.

We perform the same re-entry check as we do for non-windows platforms.

This approach pretty directly taken from: https://stackoverflow.com/questions/20337870/what-is-the-equivalent-of-system-diagnostics-debugger-launch-in-unmanaged-code

Don’t use this directly.
