Yinhang Liu b1ebe93eb2 msdkvpp: Add function to dynamically create sink caps and src caps 
We need to create the sink caps and src caps dynamically for different
platforms. By default, the vpp init function create static pad template
and the compatibility and flexibility of the platform are too poor.
