spdm: Improve Crypto trait dependency
Make 2 changes to the Crypto trait:
1. The not-yet-implemented FFI Crypto trait and the test Crypto trait
use unit type as the crypto types for convenience. As the result,
some methods are actually using wrong parameter types compared from
the Crypto trait definition, but isn't found out because those types
are all unit types. Change those unit types to different unit structs
that have the same convenience, but avoids messing up with different
param types.
2. Make `random_key_pair` specify different lifetime params for the
private key and public key, as they might have different lifetimes at
the call site.
