[PATCH] [Support] Lazy load of dbghlp.dll on Windows

[Zachary Turner]

I don't really know much about MinGW, and i also am not in a position to be
able to look at any code right now as I'm technically OOO for another 3
weeks. That said, if it is possible to make this work as a delayload dll,
it would be much preferred, even if it strays from some existing
implementation that does something different. With MSVC, this is as simple
as adding a linker flag, and you don't have to change even 1 line of code.
I'm not sure if MinGW toolchain supports this, but please check first. I'll
leave the final lgtm to someone else on this review.
