Costin Leau 0f9532689f EQL: Propagate key constraints through the query (#62073)
Since join keys are common across all queries in a Join/Sequence, any
constraint applied on one query needs to be obeyed but all the other
queries.
This PR enhances the optimizer to propagate such constraints across
all queries so they get pushed down to the actual generated ES queries.

Fix #58937
