Pedro J. Estébanez 9444d297ed WorkerThreadPool: Overhaul scheduling and synchronization 
This commits rewrites the sync logic in a way that the
`use_system_threads_for_low_priority_tasks` setting, which was added due to
the lack of a cross-platform wait-for-multiple-objects functionality, can be
removed (it's as if it was effectively hardcoded to `false`).

With the new implementation, we have the best of both worlds: threads don't
have to poll, plus no bespoke threads are used.

In addition, regarding deadlock prevention, since not every possible case of
wait-deadlock could be avoided, this commits removes the current best-effort
avoidance mechanisms and keeps only a simple, pessimistic way of detection.

It turns out that the only current user of deadlock prevention, ResourceLoader,
works fine with it and so every possible situation in resource loading is now
properly handled, with no possibilities of deadlocking. There's a comment in
the code with further details.

Lastly, a potential for load tasks never being awaited/disposed is cleared.

/* Engine initialization
*
* Consists of several methods that are called by each platform's specific main(argc, argv).
* To fully understand engine init, one should therefore start from the platform's main and
* see how it calls into the Main class' methods.
*
* The initialization is typically done in 3 steps (with the setup2 step triggered either
* automatically by setup, or manually in the platform's main).
*
* - setup(execpath, argc, argv, p_second_phase) is the main entry point for all platforms,
* responsible for the initialization of all low level singletons and core types, and parsing
* command line arguments to configure things accordingly.
* If p_second_phase is true, it will chain into setup2() (default behavior). This is
* disabled on some platforms (Android, iOS) which trigger the second step in their own time.
*
* - setup2(p_main_tid_override) registers high level servers and singletons, displays the
* boot splash, then registers higher level types (scene, editor, etc.).
*
* - start() is the last step and that's where command line tools can run, or the main loop
* can be created eventually and the project settings put into action. That's also where
* the editor node is created, if relevant.
* start() does it own argument parsing for a subset of the command line arguments described
* in help, it's a bit messy and should be globalized with the setup() parsing somehow.
