UefiCpuPkg/ArmMmuLib: Drop IPA width in ArmCcaSetMemoryProtectionAttribute

Browse source 
ArmCcaSetMemoryProtectionAttribute() now derives the Realm CCA
protection attribute internally using ArmCcaGetProtectionAttributeMask(),
so callers no longer need to pass the Realm IPA width.

Drop the IPA width parameter from the API and update callers accordingly.
