AR/FR: Updated resources to confirm via component.

Due to issues with an Intent filter not being configured with a category. We
needed to move to launching the confirmation activity via Component targeting
Intent. Hopefully this can be addressed post IC.

Manual Testing:

Start by navigating in Settings to:

Settings > System > Reset Options > Erase

Then click on "Reset Phone." At this point the behavior depends on the state of
GmsCore.

With forthcoming GmsCore changes (and accompanying SettingsGoogle changes), the  user will see a prompt telling them that
they can confirm their credentials. Regardless of whether the user successfully
confirms or hits back, they will end up in the MasterClearConfirm UX. As per the
feature spec.

Test: make RunSettingsRoboTests -j40
