DESERIALIZER: Small bugfix in the deser_process()

(Merged from https://github.com/openssl/openssl/pull/12544)

DESERIALIZER: Make OSSL_DESERIALIZER_from_{bio,fp} use BIO_tell() / BIO_seek()

Depending on the BIO used, using BIO_reset() may lead to "interesting"
results.  For example, a BIO_f_buffer() on top of another BIO that
handles BIO_reset() as a BIO_seek(bio, 0), the deserialization process
may find itself with a file that's rewound more than expected.

Therefore, OSSL_DESERIALIZER_from_{bio,fp}'s behaviour is changed to
rely purely on BIO_tell() / BIO_seek(), and since BIO_s_mem() is used
internally, it's changed to handle BIO_tell() and BIO_seek() better.

This does currently mean that OSSL_DESERIALIZER can't be easily used
with streams that don't support BIO_tell() / BIO_seek().

[test] Vertically test explicit EC params API patterns

This commit adds a new test (run on all the built-in curves) to create
`EC_GROUP` with **unknown** *explicit parameters*: from a built-in group
we create an alternative group from scratch that differs in the
generator used.

At the `EC_GROUP` layer we perform a basic math check to ensure that the
math on the alternative group still makes sense, using comparable
results from the origin group.

We then create two `EC_KEY` objects on top of this alternative group and
run key generation from the `EC_KEY` layer.

Then we promote these two `EC_KEY`s to `EVP_PKEY` objects and try to
run the derive operation at the highest abstraction layer, comparing
results in both directions.

Finally, we create provider-native keys using `EVP_PKEY_fromdata` and
data derived from the previous objects, we compute an equivalent shared
secret from these provider keys, and compare it to the result obtained

SERIALIZER: Add functions to deserialize into an EVP_PKEY

EVP_PKEY is the fundamental type for provider side code, so we
implement specific support for it, in form of a special context
constructor.

This constructor looks up and collects all available KEYMGMT
implementations, and then uses those names to collect deserializer
implementations, as described in the previous commit.

DESERIALIZER: Add foundation for deserializers

This adds a method OSSL_DESERIALIZER, a deserializer context and basic
support to use a set of serializers to get a desired type of data, as
well as deserializer chains.

The idea is that the caller can call OSSL_DESERIALIZER_CTX_add_serializer()
to set up the set of desired results, and to add possible chains, call
OSSL_DESERIALIZER_CTX_add_extra().  All these deserializers are pushed
on an internal stack.

The actual deserialization is then performed using functions like
OSSL_DESERIALIZER_from_bio().  When performing deserialization, the
inernal stack is walked backwards, keeping track of the deserialized
data and its type along the way, until the data kan be processed into
the desired type of data.

Fix: uninstantiation breaks the RAND_DRBG callback mechanism

The RAND_DRBG callbacks are wrappers around the EVP_RAND callbacks.
