Fix array texture readback with GetTexImage. According to the desktop GL specs, GetTexImage retrieves entire mips of a texture for 2D array and cube array textures. The prior code was only retrieving one layer and didn't have any way to get the layers other than layer zero. Fix this by using similar logic to how we read back 3D textures. Also adds regression tests to GetImageTest.
