FS-7500: refactor to use switch_core_video

Browse Source 
added switch_core_codec_encode_video and switch_core_codec_decode video and add separate video implementations
the switch_core_video code depends on libvpx, wraped into the switch_ namespace like switch_apr, need to figure out how to find the correct libvpx lib in autotools
