internal/restorable: optimize removeDuplicatedRegions from O((n+m)^2) to O(n*m + m^2) (#2631) 
This is achieved by replacing the function by one that only adds a single
new region, and only considers duplicates between the previously existing
region and the one newly added one, thereby removing previously redundant
checking of each previously existing region against each other.

This speeds up AAAAXY loading on a Moto G7 Play from 52.27 seconds to
8.15 seconds.

Closes #2626
