CryptoPkg: Remove deprecated function usage in X509GetCommonName()
BZ#: https://bugzilla.tianocore.org/show_bug.cgi?id=923
X509_NAME_get_text_by_NID() used in X509GetCommonName() implementation
is one legacy function which have various limitations. The returned
data may be not usable when the target cert contains multicharacter
string type like a BMPString or a UTF8String.
This patch replaced the legacy function usage with more general
X509_NAME_get_index_by_NID() / X509_NAME_get_entry() APIs for X509
CommonName retrieving.
Tests: Validated the commonName retrieving with test certificates
containing PrintableString or BMPString data.
