Split out code into new getKeyJsonValueFromContainer()
The new function stashes its output value in a JsonbValue that can be
passed in by the caller, which enables some of them to pass
stack-allocated structs -- saving palloc cycles. It also allows some
callers that know they are handling a jsonb object to use this new jsonb
object-specific API, instead of going through generic container
findJsonbValueFromContainer.
