CryptoPkg/BaseCryptLib: Add C-structure to matching certificate stack

Browse Source 
The parameter CertStack of Pkcs7GetSigners will return all embedded X.509
certificate in one given PKCS7 signature. The format is:
//
// UINT8  CertNumber;
// UINT32 Cert1Length;
// UINT8  Cert1[];
// UINT32 Cert2Length;
// UINT8  Cert2[];
// ...
// UINT32 CertnLength;
// UINT8  Certn[];
//
Add EFI_CERT_STACK and EFI_CERT_DATA structure, these two C-structure are
used for parsing CertStack more clearly.
