### What problem does this PR solve?
Issue Number: N/A
Related PR: #63529, #63766, #64102
Problem Summary:
Backport the following merged fixes to branch-4.1:
- #63529 preserves the required shuffle distribution for serial merge
aggregation.
- #63766 preserves aggregation hash shuffle after a non-hash local exchange.
- #64102 prevents unsafe runtime filter pushdown through the null-generating
side of outer joins.
The BE aggregation backports are applicable to branch-4.1 because the branch
still has the affected aggregation/local-exchange distribution paths and was
missing these fixes. The runtime filter fix is also absent from branch-4.1 and
was adapted to the branch-4.1 RuntimeFilterPushDownVisitor structure.
