Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668)
Add RngDxe support for Arm. This implementation uses the ArmTrngLib
to support the RawAlgorithm and doens't support the RNDR instruction.
To re-use the RngGetRNG(), RngGetInfo() and FreeAvailableAlgorithms()
functions, create Arm/AArch64 files which implement the arch specific
function GetAvailableAlgorithms(). Indeed, FEAT_RNG instruction is not
supported on Arm.

To re-use the AArch64/RngDxe.c for an Arm implementation,

RawAlgorithm is used to provide access to entropy that is suitable
for cryptographic applications. Therefore, add RawAlgorithm support
that provides access to entropy using the ArmTrngLib.
Also remove unused UefiBootServicesTableLib library inclusion
and Status variable.

RngGetBytes() relies on the RngLib. The RngLib might use the RNDR
instruction if the FEAT_RNG feature is present. RngGetInfo and
RngGetRNG both must check that RngGetBytes() is working before
advertising/using it.
To do so, allocate an array storing the available algorithms.
The Rng algorithm at the lowest index will be the default Rng
algorithm. The array is shared between RngGetInfo and RngGetRNG.
This array is allocated when the driver is loaded, and freed
when unloaded.
This patch also prevents from having PcdCpuRngSupportedAlgorithm
let to a zero GUID, but let the possibility to have no valid Rng
algorithm in such case.

Rename RdRandGenerateEntropy() to GenerateEntropy() to provide a
common interface to generate entropy on other architectures.
GenerateEntropy() is intended to generate high quality entropy.
Also move the definition to RngDxeInternals.h

AARCH64 support has been added to BaseRngLib via the optional
ARMv8.5 FEAT_RNG.
Refactor RngDxe to support AARCH64, note support for it in the
VALID_ARCHITECTURES line of RngDxe.inf and enable it in SecurityPkg.dsc.

Use the new RngLib to provide the IA32/X64 random data for RngDxe.
Remove x86 specific functions from RdRand files.
Simplify RngDxe by using WriteUnaligned64 for all platforms.
Use GetRandomNumber128 in RngDxe to leverage 128 bit support provided
by some HW RNG devices.
