Add TaggedScheduler, couple lifetime of tasks and orchestrator

[mwilsnd]

This PR refactors the scheduler and thread pool architecture by coupling scheduled tasks with an opaque identifier intended to represent the owner of the submitted task. This enables queries on the thread pool based on tasks submitted by a specific owner, which is relevant as the same background thread pool can be shared among multiple map instances. Knowing what tasks are scheduled by a specific owner allows us to remove any timeout conditions when waiting on all submitted work to be completed. This should result in more consistent and deterministic behavior of background tasks in multiple map scenarios.

Should probably undo #2455

[TimSylvester]

Should probably undo #2455

It'll disappear in the merge, that code was removed.

[louwers]

Very clean.

[westnordost]

If there will be a new release or beta/alpha release with this change, we could test if it solves #2410

[louwers]

@westnordost I made a pre-release. https://github.com/maplibre/maplibre-native/releases/tag/android-v11.0.2-pre0

[westnordost]

Thank you, I already added it to the branch and asked if it can still be reproduced: streetcomplete/StreetComplete#5693 (comment)
