frontends/va: Process VAEncSequenceParameterBufferType first in vaRenderPicture

The encoder is created in handleVAEncSequenceParameterBufferType and it
also sets some default parameters, so we need to make sure to handle
this buffer first because application may have already set those
parameters from earlier buffers.

This fixes setting HRD parameters with gstreamer vah264enc/vah265enc
when PIPE_VIDEO_CAP_ENC_QUALITY_LEVEL is supported.
