[rust png] Move include of `png_decoder.h` from `.h` to `.cpp` file.
This CL follows-up after https://pdfium-review.googlesource.com/135653.
That earlier CL moved `PngDecoderDelegate` into a separate `.h` file.
This move meant that `progressive_decoder.h` only 1) has to include
`png_decoder_delegate.h` and 2) does *not* need to include
`png_decoder.h` (where the `PngDecoder::Delegate` interface used to be
declared). The 2nd part was missed in the earlier CL, so _this_ CL
takes care of this: moving `#include ".../png_decoder.h"` from
`progressive_decoder.h` into `progressive_decoder.cpp`.
