From: Pierre Gondois <pierre.gondois@arm.com>

v1:
- https://edk2.groups.io/g/devel/message/96356
v2:
- https://edk2.groups.io/g/devel/message/96434
- Reformulate commit message.
- Do not warn if no algorithm is found as the message
  would be printed on non-Arm platforms.

  1. ArmPkg/ArmTrngLib: Remove ASSERTs in ArmTrngLibConstructor()
     Requested by Ard.
     Cf https://edk2.groups.io/g/devel/message/96495
  2. SecurityPkg/RngDxe: Conditionally install EFI_RNG_PROTOCOL
     Do not install EFI_RNG_PROTOCOL if no RNG algorithm is available.
     Cf. https://edk2.groups.io/g/devel/message/96494
  3. SecurityPkg/RngDxe: Fix Rng algo selection for Arm
     Coming from v2 patch being split.

Some issues were found by Ard/Sami on the RngDxe/ArmTrngLib after
recent patches were merged. This patch serie intends to fix them.
