Remove 3 wilco power policy tests

Remove tests for peak shift, battery charge mode and advanced battery
charge mode. These tests were always broken in the lab:
https://stainless.corp.google.com/search?view=matrix&row=test&col=build_version&first_date=2021-09-30&last_date=2021-10-27&suite=%5Ewilco_bve%24&exclude_cts=false&exclude_not_run=false&exclude_non_release=true&exclude_au=true&exclude_acts=true&exclude_retried=false&exclude_non_production=false

Tast tests are already migrated in Tast, but not yet stable. However,
there is no sense to keep autotest tests anymore.

Tast tests:
- policy.DevicePowerPeakShift
- policy.DeviceAdvancedBatteryChargeMode
- policy.DeviceBatteryChargeMode

BUG=b:194873632
