Enable reduceOpsTaskSplitting by default

Chrome does not rely on the default – this option is under a finch trial
named "ReduceOpsTaskSplitting." See crbug.com/1210578.

Android does not rely on the default – the flag is controlled by a
property named "renderthread.skia.reduceopstasksplitting", and enabled
by default. See b/183612348.

Flutter does not rely on the default – they explicitly disable the
option. See https://github.com/flutter/engine/pull/26568.

Our tools do not rely on the default – they enable the flag unless the
user passes --dontReduceOpsTaskSplitting on command line. Our bots
run with the flag enabled except the NUC5PPYH, for the sake of coverage.

The flag has no effect for Adreno 620 and 640, on drivers older than
v571, due to a driver bug.
