    ghc-heap: Add dependency from GHC.Exts.Heap.Closures to InfoTableProf
    
    `ghc -M` currently doesn't properly account for ways when generating
    dependencies (#15197). This import ensures correct build-ordering between this
    module and GHC.Exts.Heap.InfoTableProf. Otherwise the profiled build may fail as
    described in #15197.
