Each entry in BCC is signed by its parent. BCC validator should be able to
validate the signature along the chain.
In OPK reference, EdDSA is used. Also adding functions to support ECDSA
in oemcrypto_ecc_key module.

A Bcc validator that can parse and validate BCC. This is to support better
prov40 unit tests regarding OEMCrypto_GetBootCertificateChain() later.

[ Merge of http://go/wvgerrit/152950 ]
This CL introduces several functions for computing a HMAC-SHA256
signature. The functions wrap the OpenSSL/BoringSSL implementation
of HMAC(), allowing for common C++ types to be passed in. Several
of the functions follow several OEMCrypto conventions for generating
signatures (ex. returning OEMCrypto_ERROR_SHORT_BUFFER if signature
buffer is too small).
Also provided limited wrappers for HMAC-SHA-1, which are used for
a limited number of operations within OEMCrypto.
