This was carried from Citra and wasn't really used on yuzu. It also adds
some runtime overhead. This commit removes it from yuzu's codebase.

Allows the graphics breakpoints to compile with implicit string
conversions disabled.

This doesn't actually work anymore, and given how long it's been left in
that state, it's unlikely anyone actually seriously used it.

Generally it's preferable to use RenderDoc or Nsight to view surfaces.

- Use QStringLiteral where applicable.

- Use const where applicable

- Remove unnecessary precondition check (we already assert the pixbuf
  being non null)

We can utilize qOverload with the signal connections to make the
function deducing a little less ugly.

Fills in the missing surface types that were marked as unknown. The
order corresponds with the TextureFormat enum within
video_core/texture.h.

We also don't need to all of these strings as translatable (only the
first string, as it's an English word).

These types are within the common library, so they should be using the
Common namespace.
