Use base's DISALLOW_COPY_AND_ASSIGN in renderer/platform/{bindings,image-decoders,loader}

... as a replacement to wtf's WTF_MAKE_NONCOPYABLE.

As part of the process to phase out wtf's WTF_MAKE_NONCOPYABLE in
favor of base's DISALLOW_COPY_AND_ASSIGN, this CL does the replacement
on the aforementioned directories.

The DEPS files of the directories were also changed to prevent future
uses of WTF_MAKE_NONCOPYABLE altogether.
