Update the mechanism to upload new anomaly config

1. Move the config update to jobscheduler, so config is checked and updated every day. 2. Before the update, always delete the old config. 3. Move uploadIntent method to BatteryTipUtils. Bug: 74997752 Fixes: 74564143 Test: RunSettingsRoboTests Change-Id: If88759595d57a562b25542082f895fe8f207acdb
