Fill the 120-byte SceVideodec2AvcPictureInfo for a single owned H.264
picture queried with thisSize 0x78: SPS fields, VUI, pic_struct from the
picture-timing SEI and per-unit presence flags, parsed per ITU-T H.264
(08/2021) from the access unit that produced the picture. Layout from
SharpProspero Videodec2.cs and shadPS4 videodec2.h. Other accepted
sizes, two records and unsupported syntax still throw after the
validity clears.

OutputInfo had no member at offset 0xb, so sceVideodec2Decode and
sceVideodec2Flush never wrote that byte, and a returned picture carried
whatever the caller had left there. Name it isDiscardedFrame, as
SharpProspero and KytyPS5 do, and set it to 0 when a picture is
returned; a result without a picture leaves it as the caller set it.
