Allow copy destination to have a different scale from source (#1711)

* Allow copy destination to have a different scale from source

Will result in more scaled copy destinations, but allows scaling in some games that copy textures to the output framebuffer.

* Support copying multiple levels/layers

Uses glFramebufferTextureLayer to copy multiple layers, copies levels individually (and scales the regions).

Remove CopyArrayScaled, since the backend copy handles it now.
