Activate complex text path on Android

In Chromium commit 10749067720a341 catapult was rolled, switching to
default teardowns between pageset repeats, compare [1]. Activating
complex text on Android again after this change in order to see how
measurements are affected by this. If no memory regression shows up in
the memory health measurements for memory pagesets this would indicate
that we may have a memory-leakage over time problem in webview
single-process mode but no issues in the usual tab process lifecycle on
Android. Activating and TBR'ing to collect bot results, potentially
reverting later if needed for further investigation.
