The new EVP_DigestSqueeze() API requires changes to all keccak-based
digest provider implementations. Update the s390x-part of the SHA3
digest provider.
Squeeze for SHA3 is not supported, so add an empty function pointer
(NULL).

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.

The hardware-assisted ARMv8.2 implementation is already in keccak1600-armv8.pl.
It is not called because the author mentioned that it's not actually obvious
that it will provide performance improvements. The test on Apple M1 Firestorm
shows that the ARMv8.2 implementation could improve about 36% for large blocks.
So let's enable ARMv8.2 accelerated SHA3 on Apple CPU family.

s390x does not directly support keccak via CPACF since these instructions
hard-code the padding to either SHA-3 or SHAKE for the "compute last message
digest" function. This caused test errors on Keccak digests. Fix it by using
"compute intermediate message digest" and manually computing the padding for
Keccak.

The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all
functions which are dispatched between the core and providers.
This change includes in particular all up- and downcalls, i.e., the
dispatched functions passed from core to provider and vice versa.
- OSSL_core_ -> OSSL_FUNC_core_
- OSSL_provider_ -> OSSL_FUNC_core_
For operations and their function dispatch tables, the following convention
is used:
Type | Name (evp_generic_fetch(3)) |
---------------------|-----------------------------------|
operation | OSSL_OP_FOO |
function id | OSSL_FUNC_FOO_FUNCTION_NAME |
function "name" | OSSL_FUNC_foo_function_name |
function typedef | OSSL_FUNC_foo_function_name_fn |
function ptr getter | OSSL_FUNC_foo_function_name |

The provider- manuals are meant to describe the general interface for
their respective operation. This is not the place to describe
implementation specific details.
This change creates a number of doc/man7/EVP_MD manuals, one for each
algorithm or set of algorithms, as well as doc/man7/EVP_MD-common.pod
to describe what's common to them all.
While we're at it, correct the SHA3 settable context params array to
match what's actually settable.

From providers/{common,default,legacy}/ to providers/implementations/
However, providers/common/digests/digest_common.c stays where it is,
because it's support code rather than an implementation.
To better support all kinds of implementations with common code, we
add the library providers/libcommon.a. Code that ends up in this
library must be FIPS agnostic.
While we're moving things around, though, we move digestscommon.h
from providers/common/include/internal to providers/common/include/prov,
thereby starting on a provider specific include structure, which
follows the line of thoughts of the recent header file reorganization.
We modify the affected '#include "internal/something.h"' to
'#include "prov/something.h"'.
