Merge #6376: refactor: a bunch of trivial-ish headers improvements

e9387ee refactor: remove unused includes and forward declarations from headers (Konstantin Akimov)
f2a186f refactor: remove definition IsQuorumDKGEnabled from header (Konstantin Akimov)
8a7941b refactor: merge helper GetCoinbaseTx which is used only once into GetNonNullCoinbaseChainlock (Konstantin Akimov)

Pull request description:

  ## Issue being fixed or feature implemented
  Split from #6375 and added some extra

  ## What was done?
  Tidy up headers of evo/ and llmq/:
   - removed unused includes and added missing
   - removed unused forward declarations and added missing
   - removed helper GetCoinbaseTx, moved helper IsQuorumDKGEnabled from header to implementation

  ## How Has This Been Tested?
  Run unit and functional tests

  Compilation time _in theory_ should be improved, in really it shaved just 2-5 seconds from 5 minutes by my benchmark.

  ## Breaking Changes
  N/A

  ## Checklist:
  - [x] I have performed a self-review of my own code
  - [x] I have commented my code, particularly in hard-to-understand areas
  - [x] I have added or updated relevant unit/integration/functional/e2e tests
  - [x] I have made corresponding changes to the documentation
  - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_
