The BdsLib library has been moved into Platform/ARM a while ago, but the BdsLib.h header was left behind, and so all users in Platform/ARM are still relying on it to be available in ArmPkg.
So let's add a copy to Platform/ARM and wire it up, so we can drop it from ArmPkg going forward. Note that the BdsLib implementation included ArmLib.h from ArmPkg without using anything it provides, so drop that false dependency as well.
