[PATCH 13/18] CryptoPkg: Update code to be more C11 compliant by using __func__

["Rebecca Cran" <rebecca@bsdio.com>]

__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
CryptoPkg.

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__
