Fix PermissionsHostTest failures for automotive builds.

Some permissions are not on screen due to the display size. As a result, accessibility info was not populated as expected causing failures when granting / revoking permissions within long lists.

testGrantPreviouslyRevokedWithPrejudiceShowsPrompt23 is flaky, but from local testing, increasing the idle timeout seems to improve the success rate.
