Add facility to run tasks on dedicated threads using the ThreadManager interface.
...
Useful for things that should be run ASAP even if the threadpool is full,
at a small extra cost. (Not recommended for very small tasks).
Considering using this to resolve the deadlocks in #16802 .

ThreadManager: Don't allow reordering of queue.
...
Allowing a priority item is faster, but can cause confusion when you
expect things to run in the same sequence they're enqueued.

Strict mode checking - no way to forget detaching now.
...
And if we forget to attach, boom. Hopefully I caught all of them.

Try to get a bit better at detaching threads that have used JNI from the VM.

softgpu: Use persistent bin task state.
...
It's constant, so it's better to avoid the copying and allocation. A
small win, but removes new from the profile.

Even if expected stays null, since it's weak assume it can fail.

ThreadManager: Use separate pool for IO blocking.
...
This prevents starving the compute pool (which may be used very regularly
parallel loops or other tasks) if the IO operations are slow.

ThreadManager: Protect against teardown hang/leak.
...
Make sure we lock during canceled checks/updates, and also try to free
tasks queued on threads that didn't end up running.

ThreadManager: Lock notify on global queue add.
...
Otherwise, it's possible the chosen thread might not wake up, and then it
may wait for another task to be enqueued - potentially causing a hang.

ThreadManager: Use atomic task optimistically.
...
This makes EnqueueTaskOnThread take priority as well.
Gives about 1% improvement in softgpu, reducing overhead a bit.
