Reduce blocking calls to Settings in main thread
In most cases, mTileList contains the same information as the Settings
value, so there's no need to retrieve it before modifying it. Keep track
of that with a dirty flag.
This way, we reduce the number of blocking calls in the main thread (as
that's the thread that processes the tiles).
Test: manual, factory reset
Test: existing QSTileHostTest
Test: performance metrics are back to baseline
