Yes, we can create a host test specific lib if no better ways.

Can we use a host test specific RngLib?

Subject: CryptoPkg host test broken due to smoketest for RDRAND

All crypto host tests which consumed randlib broken due to:
https://github.com/tianocore/edk2/pull/5714
Not sure why this issue not reported  by CI when merge this PR.

The reason is that the ```BaseRngLibConstructor``` of rnglib is not called in 
host test, so ```mRdRandSupported``` is not enabled.
Then the Crypto API calls ```GetRandomNumber*``` will fail.
GetRandomNumber64 (
  OUT     UINT64  *Rand
  )
{
  ......
  if (!ArchIsRngSupported ()) {
    return FALSE;
  }

Is there a way to let unit test host to call the constructors correctly?

Regards,
Yi
