CryptoPkg: Add SecCryptLib

Browse Source 
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853

This is the Cryptographic library instance for SEC. The motivation of
this library is to support SHA384 in SEC phase for Td guest. So only
Hash/CryptSha512.c is included which supports SHA384 and SHA512. Other
cryptographics are added with the null version, such as CryptMd5Null.c.

This function receives a PKCS#7 formatted signature blob,
looks for the EKU SEQUENCE blob, and if found then looks
for all the required EKUs. This function was created so that
the Surface team can cut down on the number of Certificate
Authorities (CA's) by checking EKU's on leaf signers for
a specific product. This prevents one product's certificate
from signing another product's firmware or unlock blobs.
Note that this function does not validate the certificate chain.
That needs to be done before using this function.
@param[in] Pkcs7Signature The PKCS#7 signed information content block. An array
containing the content block with both the signature,
the signer's certificate, and any necessary intermediate
certificates.
@param[in] Pkcs7SignatureSize Number of bytes in Pkcs7Signature.
@param[in] RequiredEKUs Array of null-terminated strings listing OIDs of
required EKUs that must be present in the signature.
@param[in] RequiredEKUsSize Number of elements in the RequiredEKUs string array.
@param[in] RequireAllPresent If this is TRUE, then all of the specified EKU's
must be present in the leaf signer. If it is
FALSE, then we will succeed if we find any
of the specified EKU's.
