Split image handler plugin project files

One pri for each handler, e.g. src/gui/image/qjpeghandler.pri.
One pri for each 3rd party package, e.g src/3rdparty/libjpeg.pri.
One shared pri for zlib dependency of 3rd party packages.

This was really about image handler plugins, but PNG got the
same treatment for consistency's sake.

Also, moved image handler source files from plugins to src/gui/image
so they are with the other image handlers.
