CryptoPkg/Driver: Add Crypto PEIM, DXE, and SMM modules
https://bugzilla.tianocore.org/show_bug.cgi?id=2420
Based on the following package with changes to merge into
CryptoPkg.
https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg
Add the CryptoPei, CryptoDxe, and CryptoSmm modules that produce
EDK II Crypto Protocols/PPIs that provide the same services as
the BaseCryptLib class.
In order to optimize the size of CryptoPei, CryptoDxe, and
CryptoSmm modules for a specific platform, the FixedAtBuild
PCD gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable
is used to determine if a specific service is enabled or
disabled. If a service is enabled, then a call is made to
the BaseCryptLib service. If the service is disabled, then
a DEBUG() message and ASSERT() are performed and a default
return value is returned. This provides simple detection
of a service that is disabled but is used by another module
when DEBUG()/ASSERT() macros are enabled.
The use of a FixedAtBuild PCD is required so the compiler
and linker know each services enable/disable setting at
build time and allows disabled services to be optimized away.
CryptoPei supports both pre-mem and post-mem use cases.
If CryptoPei is initially dispatched pre-mmem, the the
register for shadow service is used so the Crypto PPI can
be reinstalled post-mem.
