Add api to change charging state update delay

This adds a field Settings.Global.BATTERY_CHARGING_STATE_UPDATE_DELAY
that overrides the value of battery_charged_delay_ms in
Settings.GLOBAL.BATTERY_STATS_CONSTANTS.

This new field can then be set for experimentation, and easily reset to
default by deleting, or setting it to a negative value.

Expose a method in BatteryManager to set a value for this new setting.

Bug: 111360323
Test: adb shell settings put global battery_charging_state_update_delay 999
adb shell dumpsys batterystats --settings # should see battery_charged_delay_ms=999
adb shell settings put global battery_charging_state_update_delay -1
adb shell dumpsys batterystats --settings # should see battery_charged_delay_ms=90000
