WindowsDynLib lookup function should pass a C String to GetProcAddress

[rivten]

In here : https://github.com/ziglang/zig/blob/master/std/dynamic_library.zig#L197 , the function lookup should either : receive a C String as an input (c"MyLookupName") or reformat the Zig String input to C String. This is because GetProcAddress expects a C String.

this should be solved by #265, but in the mean time, i can't think of a correct solution that doesn't require a comptime, an allocator, of the user null-terminating the string themselves.

One thing you can do for now is have a buffer on the stack with, say, 512 bytes. If the length is too big for this return error.NameTooLong or similar. We can always improve this API later.

Solved with #265 and #2598
