mAvailableAlgoArray is currently allocated for "RNG_AVAILABLE_ALGO_MAX"
number of bytes, whereas it was dereferenced as "EFI_RNG_ALGORITHM".
This change fixed the buffer allocation logic by allocating a proper size
of buffer before referencing.

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.
