The password generation has launched on all platforms and was enabled by default with M70.

For Android, there is no code path that would give a user access to the generation itself but the client-side metrics and other operations preparing the generation would happen anyway. To see differences in stability, it makes more sense to disable the feature per default and enable it via Finch as opposed to disabling it via Finch.

Therefore, I would like to merge https://crrev.com/c/1226605 which already landed:

[Android] Disable automatic password generation by default

disabled via Finch.

This CL ensures that Finch only enables this which is a healthier
default as Finch isn't meant as a rollout control tool but for
experimenting.
