vaencoder: Add gst_va_encoder_get_reconstruct_pool_config()

Browse source 
This method will return the caps configured in the reconstruct buffer
pool, and its maxium number of buffers to allocate.

The caps are needed later to know if the internal encoder has to be
reopened if the stream properties change.
