ArmPkg: allow patchable PCDs for memory, FD and FV addresses
In order to allow a runtime self relocating PrePi instance, change the
allowable PCD types for the following PCDs:
gArmTokenSpaceGuid.PcdSystemMemoryBase
gArmTokenSpaceGuid.PcdSystemMemorySize
gArmTokenSpaceGuid.PcdFdBaseAddress
gArmTokenSpaceGuid.PcdFvBaseAddress
to include PcdsPatchableInModule. This makes the build system correctly
distinguish fixed PCDs from PCDs whose value may be different from the
assigned value at compile time.
Note that this only affects platforms that explicitly mark these PCDs as
PatchableInModule in the DSC. All existing platforms that use FixedPcd
will not be affected by this change.
