add ability to open dlls with platform-specific flags

[wozniak]

Only implemented for Windows right now, I'm not sure that I've written any of this correctly but the idea is there. Please give me feedback as I still have not actually written real zig anywhere before.

reading https://learn.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-loadlibraryexw, LoadLibraryFlags looks like it should be an enum instead

Ah, you're right. I must have missed "one of the following values".
