charge_manager: Enter safe mode at boot
Charge port / current selection often needs to be significantly altered when a battery cannot provide sufficient charge, so have charge_manager initially enter safe mode. After a battery with sufficient capacity has been identified, charge manager will leave safe mode, and port / current selection will return to standard rules. BUG=chromium:777596 BRANCH=None TEST=Pass charge_manager unit tests. On kevin, remove battery, attach Apple PD charger, verify safe mode is not exited and device does not brown out. Hot-plug battery and verify safe mode is exited. Next, remove battery, attach to Samus, verify safe mode is not exited and device doesn't brown out. Hot-plug battery, verify that safe mode is exited and no active charge port, due to dual-role exclusion.
