media: venus: helpers: add three more helper functions 

This adds three more helper functions:
 * for internal buffers reallocation, applicable when we are doing
dynamic resolution change
 * for initial buffer processing of capture and output queue buffer
types

All of them will be needed for stateful Codec API support.
