[prism] Java timer families cannot be looked up SDK side (prism re-write issue) #32221
Description
Java SDK timer tests fail, being unable to look up timers SDK side, even though the Go and Python SDKs don't seem to have this issue.
The error occurs in BeamFnDataInboundObserver.
error="bundle inst003 stage-004 failed:java.lang.IllegalStateException: Unable to find inbound timer receiver for instruction \"inst003\", transform \"first-ParMultiDo-Anonymous-\", and timer family \"\" No endpoint. Available keys: [ts-foo]\n\tat org.apache.beam.sdk.fn.data.BeamFnDataInboundObserver.multiplexElements(BeamFnDataInboundObserver.java:193 ...
So we do see that there is a timer there, so question is why does it look like Prism isn't actually populating the timer family being sent to the SDK.
Full Suite iteration (two suites)

Going to iterate with the following to investigate.
