gstelementfactory: Add MEDIA_HARDWARE klass classifier

Browse source 
The Harware factory type classifier allows elements (decoders and encoders,
mostly) to advertize they rely on hardware devices to perform encoding or
decoding operations. This classifier can be used by applications to filter and
select only the elements that use hardware devices, for instance to ensure
zero-copy support is enabled for a specific pipeline.
