Add support for embedding data in generated C++ code

Browse source 
This allows compiling with SIXTYFPS_EMBED_RESOURCES=true and
images/fonts are embedded as inline variables.

Generated data is emitted into the header file as

   inline uint8_t sfps_embedded_resources_123[789] = {
       0x1, 0x2, 0x3,
   };
