Support null-eq join (#10788)

ref #10787

Support null-eq join in TiFlash by plumbing join metadata from DAG/planner into join execution,
handling nullable null-eq keys correctly in hash join, refining row-filter/null-key handling for
outer/full join paths, disabling incompatible runtime-filter paths, and adding targeted test coverage.
This branch also keeps the existing json_object pushdown changes already present on the branch.
