Add battery to AOD

Showing battery percentage in AOD in the keyguard
indication area when also randomizing the text field
position to avoid burn-in.

Removed charging indication from KeyguardStatusView
since now it's always visible in the indication area.

Bug: 64155983
Test: flash taimen, look at AOD
Test: flash walleye, look at AOD
Test: unplug device, look at message
Test: wait for change in battery level in AOD
