FIPS KAS requires use of ECC CDH.
The EC 'B' and 'K' curves have a cofactor that is not 1, and this
MUST be multiplied by the private key when deriving the shared secret.

This changes the logic to always do the security checks and then decide
what to do based on if this passes or not. Failure of a check causes
either a failure OR the FIPS indicator callback to be triggered.

Fix #23448
`EVP_PKEY_CTX_add1_hkdf_info()` behaves like a `set1` function.
Fix the setting of the parameter in the params code.
Update the TLS_PRF code to also use the params code.

Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.
There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called. Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.
Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

The code is derived from @sftcd's work in PR #17172.
This PR puts the DHKEM algorithms into the provider layer as
KEM algorithms for EC and ECX.
This PR only implements the DHKEM component of HPKE as specified in
RFC 9180.
crypto/hpke/hpke_util.c has been added for fuctions that will
be shared between DHKEM and HPKE.
API's for EVP_PKEY_auth_encapsulate_init() and EVP_PKEY_auth_decapsulate_init()
have been added to support authenticated encapsulation. auth_init() functions
were chosen rather that a EVP_PKEY_KEM_set_auth() interface to support
future algorithms that could possibly need different init functions.
Internal code has been refactored, so that it can be shared between the DHKEM
and other systems. Since DHKEM operates on low level keys it needs to be
able to do low level ECDH and ECXDH calls without converting the keys
back into EVP_PKEY/EVP_PKEY_CTX form. See ossl_ecx_compute_key(),
ossl_ec_public_from_private()
DHKEM requires API's to derive a key using a seed (IKM). This did not sit
well inside the DHKEM itself as dispatch functions. This functionality
fits better inside the EC and ECX keymanagers keygen, since
they are just variations of keygen where the private key is generated
in a different manner. This should mainly be used for testing purposes.
See ossl_ec_generate_key_dhkem().
It supports this by allowing a settable param to be passed to keygen
(See OSSL_PKEY_PARAM_DHKEM_IKM).
The keygen calls code within ec and ecx dhkem implementation to handle this.
See ossl_ecx_dhkem_derive_private() and ossl_ec_dhkem_derive_private().
These 2 functions are also used by the EC/ECX DHKEM implementations to generate
the sender ephemeral keys.

libimplementations.a was a nice idea, but had a few flaws:
1. The idea to have common code in libimplementations.a and FIPS
sensitive helper functions in libfips.a / libnonfips.a didn't
catch on, and we saw full implementation ending up in them instead
and not appearing in libimplementations.a at all.
2. Because more or less ALL algorithm implementations were included
in libimplementations.a (the idea being that the appropriate
objects from it would be selected automatically by the linker when
building the shared libraries), it's very hard to find only the
implementation source that should go into the FIPS module, with
the result that the FIPS checksum mechanism include source files
that it shouldn't
To mitigate, we drop libimplementations.a, but retain the idea of
collecting implementations in static libraries. With that, we not
have:
libfips.a
Includes all implementations that should become part of the FIPS
provider.
liblegacy.a
Includes all implementations that should become part of the legacy
provider.
libdefault.a
Includes all implementations that should become part of the
default and base providers.
With this, libnonfips.a becomes irrelevant and is dropped.
libcommon.a is retained to include common provider code that can be
used uniformly by all providers.

We had some FIPS global variables that were based on values from the

they could be based on different config files which would cause this to

Validation checks were moved into EVP_PKEY_derive_set_peer() which broke
an external negative test. Originally the old code was semi working by checking the peers public key was in the range of other parties p. It was not actually ever
checking that the domain parameters were consistent between the 2
parties. It now checks the parameters match as well as validating the
peers public key.

The X942 KDF had been modified so that it supports all optional fields - not
just the fields used by CMS.
As there are 2 types of KDF for X942 - this has been made a bit clearer
by adding an X942KDF-ASN1 alias. X942KDF-CONCAT has also been added as an
alias of X963KDF.
This work was instigated as a result of the ACVP tests optionally being
able to use keybits for the supp_pubinfo field.
Setting the parameter OSSL_KDF_PARAM_X942_USE_KEYBITS to 0 allows this
to be disabled.
