charge_manager: Add charge port override functionality
Allow a charge port to be selected as the override port, which means it
will always be selected as the charge port, if any charge supplier is
available.
BUG=chrome-os-partner:32003
TEST=Attach PD charger and BC1.2 charger. Verify that active charge port
switches to BC1.2 after running `chargeoverride [port]` from console.
Also, pass unit tests.
BRANCH=Samus
