[FLINK-5915] [table] forward the entire aggregate ArgList to aggregate
runtime functions
This PR partially solved "FLINK-5915 Add support for the aggregate on multi
fields".
The roadmap of UDAGG would be 1. codeGen all the runtime aggregate
functions; 2. add UDAGG tableAPI interface.
I would like to kick this PR off earlier as: a) we can finalize the runtime
function while doing the codeGen; b) as more and more (over) aggregates are
implemented, it would be good if we can finalize the interface and share
library to the stage (as we planned) as earlier as possible.
Note that: though the entire aggregate ArgList is forwarded to the runtime
function, for the functions that have not been codeGened, we will still support
only one column aggregate input.
