MdeModulePkg/Rng: Add GUID to describe unsafe Rng algorithms
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4441
The EFI_RNG_PROTOCOL can rely on the RngLib. The RngLib has multiple
implementations, some of them are unsafe (e.g. BaseRngLibTimerLib).
To allow the RngDxe to detect when such implementation is used,
a GetRngGuid() function is added in a following patch.
Prepare GetRngGuid() return values and add a gEdkiiRngAlgorithmUnSafe
to describe an unsafe implementation, cf. the BaseRngLibTimerLib.
