Cycle-count display is a junk format string (Windows)

[RetroEdit]

I happened to open up a recent mGBA (specifically, 0.9-6257-cdf9105f56182a207662c93da1e7a3a7f6bb2040) for some testing. I noticed cycle count had been added to the debugger. However, it just displays as %I64u on Windows.

This looks like a similar type of issue as #1794.

That shouldn't be possible...I don't use that format string anymore. I wonder what's going on.
