CryptoPkg: Fix OpenSSL BN wordsize and OPENSSL_SYS_UEFI handling

We were manually setting -DSIXTY_FOUR_BIT_LONG or -DTHIRTY_TWO_BIT on
the compiler command line when building OpensslLib itself, but not when
building BaseCryptLib.

But when building BaseCryptLib, we weren't setting OPENSSL_SYS_UEFI
*either*. This meant that *that* build was picking up the definition
from <openssl/opensslconf.h>, and was thus *different* to the version
the library was built with, in some cases.

So set OPENSSL_SYS_UEFI consistently in OpensslSupport.h and *also*
define either SIXTY_FOUR_BIT or THIRTY_TWO_BIT there too.
