Ensure EnqueuedPixelWorker does not do IO work on main thread

Task/Issue URL: https://app.asana.com/1/137249556945/project/608920331025315/task/1211922784726284?focus=true

Description

Moves work which can trigger IO to an io dispatcher instead of main and Default dispatchers that can be used currently.

Steps to test this PR

Add logcat filter: unsent clear data pixels|Pixel sent: ml|Pixel sent: mf

ml pixel

• Launch the app; verify you see ml pixel sent
• Switch to another app, then switch back to our app (it's not always enough just to background it and return). verify you see the ml pixel sent

mf pixel

• Apply patch (which triggers the background worker to run immediately on app launch instead of waiting for it to run after a few hours); install and launch app
• Use the fire button a few times (n times) to clear data
• Switch to another app, then switch back to ours; verify you see Found n unsent clear data pixels and n instances of Pixel sent: mf
