DeviceIdleController updates AMS with temp allowlist type.

1. add a "type" parameter to AMS.updateDeviceIdleTempWhitelist() which is
called by DeviceIdleController.
2. The default temp allowlist type is TEMPORARY_WHITELIST_TYPE_FOREGROUND_SERVICE_ALLOWED
which allows BG-FGS launch.
3. AMS.tempWhitelistUidLocked() already has a type parameter. Other API
to add temp allowlist can also add type parameter other than the
default.
