fix(texture_cache): handle GPU-modified ignored textures

Browse Source 
Fix UNIMPLEMENTED assertion when handling GPU-modified ignored textures
in texture cache. When ignored textures (remapped or same address/size)
have GpuModified flag set, now properly copies data to new image if
formats match, or marks new image as modified otherwise.
