  Adds the fucnction addDependentDirectory to Q, resolving issue #26148.
  
  This function adds a new directory to the list of things a module depends upon. That means that when the contents of the directory change, the recompilation checker will notice this and the module will be recompiled. Documentation has also been added for addDependentFunction and addDependentDirectory in the user guide.

  rts: Disable --eventlog-flush-interval unless compiled with -threaded.
  
  This commit fixes issue #26222:
  Using --eventlog-flush-interval with the non-threaded RTS leads to eventlog corruption.
  https://gitlab.haskell.org/ghc/ghc/-/issues/26222
  
  This commit makes three changes when code is compiled against the non-threaded RTS:
  
  1. It disables the --eventlog-flush-interval flag.
  2. It disables the documentation for the --eventlog-flush-interval flag.
  3. It disables the relevant state from RtsConfig and code from Timer.
  4. It updates the entry for --eventlog-flush-interval in the users guide.
