vpp: add vframe src_fmt struct and function [1/1]

PD#SWPL-17729

Problem:
In new video pipeline, vfm map is changed. So vpp
can not get aux data from decode directly. It cause
the format of dv or hdr10+ content is incorrect.

Solution:
Add src_fmt struct in vframe, and whole src_fmt interface.
Let front-end updates src_fmt directly. Then vpp, dv or
hdr10+ module can get the sei data from it.
