libs: encoder: vp8,h264,h265,mpeg2: refactor misc parameters

Browse source 
This is patch pretends to decouple the assignation of the values
in the parameter structures and the VA buffer's parameters setting.

It may lead to some issues since HRD, framerate or controlrate may
not be handled by the specific encoder, but they are set in
the VA buffer's parameters.

I leave as it because this patch is just a transitional patch.
