Enable both static and dynamically linked libpng

All platforms except android are configured to use the statically linked copy of libpng.  Android uses the system provided dynamic copy for SkImageDecoder and the static copy for SkCodec. The exception being android framework builds that currently use the dynamic copy everywhere.

This CL also enables NEON optimizations for libpng.

 Description: png compression/decompression library
-Local Modifications: Created pnglibconf.h from pnglibconf.h.prebuilt (just a
-    rename). Pulled LICENSE into its own file.
+Local Modifications: (1) Created pnglibconf.h from pnglibconf.h.prebuilt (a

 FAQ:
 Q: Why does this directory exist?
 A: libpng is pulled in through DEPS, but in order to build it using ninja, we
-   need to create pnglibconf.h. In https://codereview.chromium.org/930283002/,
-   we originally tried creating the file as an action, but this apparently led
-   to a race condition on Windows, where some builds failed to create the file
-   in time for other files to include it. By checking pnglibconf.h directly
-   into Skia, we eliminate the race condition.
