libs: encoder: h264,h265: initial and minimal QP can be zero

Browse source 
Currently the minimal value for either min_qp and init_qp are 1,
but VA documentation specifiy that zero is also valid and means
to ignore the quantiser.

The default value is not changed though to avoid behaivor changes
to users.
