lavc/hevcdec: move HEVCContext.sao_pixel_buffer_[vh] to HEVCLayerContext

Browse Source 
Handle them together with other sps-dependent arrays.

Note that current code only allocates these arrays when hwaccel is not
set, but this is wrong as the relevant code runs BEFORE get_format() is
called and hence before we know whether hwaccel is in use.
