st/omx/dec/h265: decoder size should follow from sps

The video size from format container is not always compatible with
the size from codec bitstream, the HW decoder should take the size
information from bitstream, otherwise the corruption appears with clip
that has different size info between bitstream and format container

So we are passing width(height)_in_samples from sequence parameter
set to video decoder.
