crypto: hash: use DM providers from hash command

The hash command currently always uses the software implementation for
the selected algorithm, even when driver-model hash providers are
available.

Add a hash_digest_wd_lookup() helper which probes UCLASS_HASH devices in
order and uses the first provider supporting the requested algorithm.
Continue past unavailable providers and unsupported operations, but
propagate a hard digest failure once a provider accepts the operation.
Remember probe failures so they are not silently hidden by software
fallback when no later provider succeeds.

Use the helper from the hash command and retain its software fallback
when no usable provider is present. Add sandbox tests covering provider
fallback and hard-error propagation.
