Merge #5961: feat: implement read write locks in threading and use them for CActiveMasternodeManager::cs

Browse Source 
069282611c refactor: make CActiveMasternodeManager::cs SharedMutex and private (pasta)
663774c544 feat: implement Read Write Locks in threading (pasta)

Pull request description:

  ## Issue being fixed or feature implemented
  We have some caches or other information in codebase which are read from a lot; but rarely written to. We can use a RW lock here instead of a normal Mutex

  ## What was done?
  Implement a RW lock and use them

  ## How Has This Been Tested?
  Hasn't been much; looking for review atm. Maybe should deploy this on testnet for a bit and make sure it doesn't break.
  ## Breaking Changes

  ## Checklist:
    _Go over all the following points, and put an `x` in all the boxes that apply._
  - [x] I have performed a self-review of my own code
  - [x] I have commented my code, particularly in hard-to-understand areas
  - [ ] I have added or updated relevant unit/integration/functional/e2e tests
  - [ ] 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)_
