Reset only failed tasks in reset_threads!

[efaulhaber]

Based on JuliaSIMD/ThreadingUtilities.jl#58.
Closes #159.

#154 caused Trixi.jl CI to freeze sometimes.
I don't have a MWE for this, but the solution is to only re-initialize failed tasks.

To summarize the previous developments:

• ThreadingUtilities.checktask did not throw an error, which means that threads with errors just failed silently (Threads fail silently on error #153).
• Throw an error in checktask when a task failed ThreadingUtilities.jl#54 changed this behavior to throw an error.
• Polyester.reset_threads! also used checktask, which now throws errors, so Avoid throwing exceptions in reset_threads! #154 changed this to call ThreadingUtilities.initialize_task instead of checktask. However, this initializes all tasks, not just the failed ones like before all of these PRs. Apparently, this can cause freezing.
• Add function reinit_task ThreadingUtilities.jl#58 adds reinit_task, which is the same as the old checktask and this PR uses this in reset_threads!.

@oscardssmith could you please have a look at this?

I would appreciate a test for this, but otherwise, LGTM

Not sure what to test here, as I can't reproduce the error this PR is fixing. It is useful to test that reset_threads! doesn't throw errors, but that test already exists (and failed after JuliaSIMD/ThreadingUtilities.jl#54 and before #154).

Could you please also add a new release?
