host: Add dcrypto definitions that can be used by fuzzing targets.
These definitions provide the necessary dcrypto functionality for
fuzzing pinweaver. They can be built out as needed to support
further fuzzing.
BRANCH=none
BUG=chromium:876582
TEST=make -j buildfuzztests &&
./build/host/cr50_fuzz/cr50_fuzz.exe (with the cr50_fuzz CL)
