Add support for H.264 Hi444PP in VDPAU API

The current patch adds a new struct VdpPictureInfoH264Predictive which
contains the necessary fields to support High 444 Predictive Profile.

The patch adds VDP_DECODER_PROFILE_H264_HIGH_444_PREDICTIVE (currently
only with 8 bit depth support). Additional profiles and levels will
be added in a future update.

Videos of VDP_DECODER_PROFILE_H264_HIGH_444_PREDICTIVE profile must use
VdpPictureInfoH264Predictive.

This patch adds lossless decode support to VDPAU API via the
qpprimey_zero_transform_bypass_flag in struct
VdpPictureInfoH264Predictive.
