Adds switch for downgrading to coarse location

Within the updated permission prompt, users will have the ability to downgrade an app to use coarse location. To ensure consistency after the main location permission prompt update, a switch view has been added to the AutoAppPermissionFragment, so that users can maintain control over these permission levels.

Bug: b/346369736

Flag: com.android.permission.flags.enable_coarse_fine_location_prompt_for_aaos

Test: manuel testing

LOW_COVERAGE_REASON=(FLAG_NOT_ENABLED| b/346369736)
