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.
