crypto: sha3 - Reimplement using library API
Replace sha3_generic.c with a new file sha3.c which implements the SHA-3
crypto_shash algorithms on top of the SHA-3 library API.
Change the driver name suffix from "-generic" to "-lib" to reflect that
these algorithms now just use the (possibly arch-optimized) library.
This closely mirrors crypto/{md5,sha1,sha256,sha512,blake2b}.c.
Implement export_core and import_core, since crypto/hmac.c expects these
to be present. (Note that there is no security purpose in wrapping
SHA-3 with HMAC. HMAC was designed for older algorithms that don't
resist length extension attacks. But since someone could be using
"hmac(sha3-*)" via crypto_shash anyway, keep supporting it for now.)
