s390x: support CPACF sha3/shake performance improvements

On newer machines the SHA3/SHAKE performance of CPACF instructions KIMD and KLMD
can be enhanced by using additional modifier bits. This allows the application
to omit initializing the ICV, but also affects the internal processing of the
instructions. Performance is mostly gained when processing short messages.

The new CPACF feature is backwards compatible with older machines, i.e. the new
modifier bits are ignored on older machines. However, to save the ICV
initialization, the application must detect the MSA level and omit the ICV
initialization only if this feature is supported.

Add EVP_DigestSqueeze() API.

Fixes #7894

This allows SHAKE to squeeze multiple times with different output sizes.

The existing EVP_DigestFinalXOF() API has been left as a one shot
operation. A similar interface is used by another toolkit.

The low level SHA3_Squeeze() function needed to change slightly so
that it can handle multiple squeezes. This involves changing the
assembler code so that it passes a boolean to indicate whether
the Keccak function should be called on entry.
At the provider level, the squeeze is buffered, so that it only requests
a multiple of the blocksize when SHA3_Squeeze() is called. On the first
call the value is zero, on subsequent calls the value passed is 1.

This PR is derived from the excellent work done by @nmathewson in
https://github.com/openssl/openssl/pull/7921

Move digests to providers

Move digest code into the relevant providers (fips, default, legacy).
The headers are temporarily moved to be internal, and will be moved
into providers after all external references are resolved. The deprecated
digest code can not be removed until EVP_PKEY (signing) is supported by
providers. EVP_MD data can also not yet be cleaned up for the same reasons.
