CryptoPkg/BaseCryptLib: Use accessor functions for ASN1_OBJECT

CryptoPkg/BaseCryptLib: Use accessor functions for ASN1_OBJECT

OpenSSL 1.1 introduces new OBJ_get0_data() and OBJ_length() accessor
functions and makes ASN1_OBJECT an opaque type.

Unlike the accessors in previous commits which *did* actually exist
already but just weren't mandatory, these don't exist in older versions
of OpenSSL. So introduce macros which do the right thing, for
compatibility.
