Subject: ArmPlatformPkg/Bds: Add a signature in front of the Boot Argument
 propoer to this Bds

Each application loader has its own OptionalData format. To avoid to start a Boot Entry
that has not been created by ArmPlatform/Bds a signature has been added to the
OptionalData.


ArmPlatformPkg/Bds: Rename some internal structure from BDS_* to ARM_BDS_*
