Use std::string in DeviceProductInfo and serialize it as Flattenable
Use std::string instead of fixed size char arrays. Serialize
DeviceProductInfo and DisplayInfo as Flattenable instead of using
memcpy().
Bug: 145299597
Test: 1. m
2. adb shell dumpsys display
3. check that DeviceProductInfo is correctly populated
