bsd: Fix eventfd broken logic (#3647)
* bsd: Fix eventfd broken logic

This commit fix eventfd logic being broken.

The following changes were made:
- EventFd IPC definition had argument inverted
- EventFd events weren't fired correctly
- Poll logic was wrong and unfinished for eventfd
- Reintroduce workaround from #3385 but in a safer way, and spawn 4
  threads.

* ipc: Rework a bit for multithreads

* Clean up debug logs

* Make server thread yield when managed lock isn't availaible

* Fix replyTargetHandle not being added in the proper locking scope

* Simplify some scopes

* Address gdkchan's comments

* Revert IPC workaround for now

* Reintroduce the EventFileDescriptor workaround
