ArmPkg/BdsLib: Upgrade the library to use natively the Device Path

Browse Source 
The previous version was using the string representation of the Device Path.
This new version takes as paramater the binary representation of the Device Path

It also tries to detect which kind of device support it refers by using the remaining
part of the Device Path after it has been loaded by gBS->ConnectController()

Lots of bug have been fixed as well in this new version.
