Pierre Gondois 1715d67231 MdePkg/BaseRngLib: Prefer ArmReadIdAA64Isar0Reg() over ArmReadIdIsar0() 
A ArmReadIdAA64Isar0Reg() function was recently added
to BaseLib. Use it instead of its ArmReadIdIsar0() equivalent,
which was private to the BaseRngLib library.

This also allows to avoid the confusion between the following
registers:
- ID_ISAR0_EL1: allows to probe for Divide instructions, Debug
  instructions, ...
- ID_AA64ISAR0_EL1: AARCH64 specific register allowing to probe
  for AESE, RNDR, ... instructions

Rebecca Cran 9301e5644c MdePkg/BaseRngLib: Add support for ARMv8.5 RNG instructions 
Make BaseRngLib more generic by moving x86-specific functionality into
'Rand' and adding files under 'AArch64' to support the optional ARMv8.5
RNG instruction RNDR that is a part of FEAT_RNG.
