Add a png.imp for include-what-you-use.

The png.h header provides some macros and declarations from subincludes.
By default include-what-you-use will suggest using these subincludes
directly, but this was not the intent of png.h. This adds a mapping file
so that include-what-you-use knows that these subincludes are actually
private and png.h should be used instead.
