crypto: sig - Introduce sig_alg backend
Commit 6cb8815f41a9 ("crypto: sig - Add interface for sign/verify")
began a transition of asymmetric sign/verify operations from
crypto_akcipher to a new crypto_sig frontend.
Internally, the crypto_sig frontend still uses akcipher_alg as backend,
however:
"The link between sig and akcipher is meant to be temporary. The
plan is to create a new low-level API for sig and then migrate
the signature code over to that from akcipher."
https://lore.kernel.org/r/[email protected]/
"having a separate alg for sig is definitely where we want to
be since there is very little that the two types actually share."
https://lore.kernel.org/r/[email protected]/
Take the next step of that migration and augment the crypto_sig frontend
with a sig_alg backend to which all algorithms can be moved.
During the migration, there will briefly be signature algorithms that
are still based on crypto_akcipher, whilst others are already based on
crypto_sig. Allow for that by building a fork into crypto_sig_*() API
calls (i.e. crypto_sig_maxsize() and friends) such that one of the two
backends is selected based on the transform's cra_type.

crypto: sig - Add interface for sign/verify
Split out the sign/verify functionality from the existing akcipher
interface. Most algorithms in akcipher either support encryption
and decryption, or signing and verify. Only one supports both.
As a signature algorithm may not support encryption at all, these
two should be spearated.
For now sig is simply a wrapper around akcipher as all algorithms
remain unchanged. This is a first step and allows users to start
allocating sig instead of akcipher.
