ArmPkg/ArmLib: move ArmReadIdPfr0/1 into private header ArmV7Lib.h

ArmReadIdPfr0 () and ArmReadIdPfr1 () are now used only inside ArmLib.
Remove the prototypes from the public header to discourage new id
register accessor additions, and direct id register access in general.
Move them into local header Arm/ArmV7Lib.h.
