Summary

This PR changes how SdlService is started from the RS via a Pending Intent from getForegroundService to getService.

We can make this change because the RS is already in the Foreground at this point, we still need SdlService to enter the foreground as Android will still shut down the service after a time if the app is not in the Foreground. |

This will help with the issue of the RemoteServiceException$ForegroundServiceDidNotStartInTimeException that has been seen in SDL apps that are not able to enter the foreground in the 5-second time allotment by Android if a phone is to slow or bogged down.
