Lioncash 6fbbc2683e VideoCommon: Make use of fmt outside of shader generators 
Migrates most of VideoCommon over to using fmt, with the exception being
the shader generator code. The shader generators are quite large and
have more corner cases to deal with in terms of conversion (shaders have
braces in them, so we need to make sure to escape them).

Because of the large amount of code that would need to be converted, the
conversion of VideoCommon will be in two parts:

- This change (which converts over the general case string formatting),
- A follow up change that will specifically deal with converting over
  the shader generators.

// 3d commands are issued through the fifo. The GPU draws to the 2MB EFB.
// The efb can be copied back into ram in two forms: as textures or as XFB.
// The XFB is the region in RAM that the VI chip scans out to the television.
// So, after all rendering to EFB is done, the image is copied into one of two XFBs in RAM.
// Next frame, that one is scanned out and the other one gets the copy. = double buffering.
