Set the ForegroundServiceType for TransferService

[mattcreaser]

Issue #, if available:
#3617

Description of changes:
Starting on API 34, foreground services must supply a foreground service type. Our service type is data sync, which corresponds to a service that uploads or downloads data.

In addition to supplying this type in code, customers must make some changes to their application manifest:

• Add the service type permission
• Add the service type to the service declaration

The manifest should look something like this:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE_DATA_SYNC"/>

    <application>
        <service
            android:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService"
            android:foregroundServiceType="dataSync" />

    </application>
