[cryptolib, test] Remove duplicate digest size references.

Previously, digest_len parameters were defined in individual tests. These are now exposed through hash.h. OTBN-based sha2 references/headers are also removed, as necessary parameters are now exposed through hash.h. Signed-off-by: Fatih Balli <[email protected]>
