The EFI_RNG_PROTOCOL can use 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,
add a GetRngGuid() function to the RngLib.

The DxeRngLib tries to generate a random number using the 3 NIST
SP 800-90 compliant DRBG algorithms, i.e. 256-bits CTR, HASH and HMAC.
If none of the call is successful, the fallback option is the default
RNG algorithm of the EFI_RNG_PROTOCOL. This default algorithm might
be an unsafe implementation.
Try requesting the Raw algorithm before requesting the default one.

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
MdePkg.
Visual Studio versions before VS 2015 don't support __func__ and so
will fail to compile. A workaround is to define __func__ as
__FUNCTION__ :
#define __func__ __FUNCTION__

This adds a RngLib that uses the RngProtocol to provide randomness.
This means that the RngLib is meant to be used with DXE_DRIVERS.
