dc010ca6ec CORE: Encure that cached fetches can be done per provider
This mostly entails passing around a provider pointer, and handling
queries that includes a pointer to a provider, where NULL means "any".

This also means that there's a need to pass the provider pointer, not
just down to the cache functions, but also be able to get it from
ossl_method_store_fetch().  To this end, that function's OSSL_PROVIDER
pointer argument is modified to be a pointer reference, so the
function can answer back what provider the method comes from.

Test added.

839ffdd11c EVP: Allow a fallback for operations that work with an EVP_PKEY
Functions like EVP_PKEY_sign_init() do an implicit fetch of the
operation implementation (EVP_SIGNATURE in this case), then get the
KEYMGMT from the same provider, and tries to export the key there if
necessary.

If an export of the key isn't possible (because the provider that
holds the key is an HSM and therefore can't export), we would simply
fail without looking any further.

This change modifies the behaviour a bit by trying a second fetch of
the operation implementation, but specifically from the provider of
the EVP_PKEY that's being used.  This is done with the same properties
that were used with the initial operation implementation fetch, and
should therefore be safe, allowing only what those properties allow.

5246183e7a EVP: Reverse the fetch logic in all pkey using functionality
In all initializing functions for functionality that use an EVP_PKEY, the
coded logic was to find an KEYMGMT implementation first, and then try to
find the operation method (for example, SIGNATURE implementation) in the
same provider.

This implies that in providers where there is a KEYMGMT implementation,
there must also be a SIGNATURE implementation, along with a KEYEXCH,
ASYM_CIPHER, etc implementation.

The intended design was, however, the opposite implication, i.e. that
where there is a SIGNATURE implementation, there must also be KEYMGMT.

This change reverses the logic of the code to be closer to the intended
design.

There is a consequence; we now use the query_operation_name function from
the KEYMGMT of the EVP_PKEY given by the EVP_PKEY_CTX (ultimately given by
the application).  Previously, we used the query_operation_name function
from the KEYMGMT found alongside the SIGNATURE implementation.

Another minor consequence is that the |keymgmt| field in EVP_PKEY_CTX
is now always a reference to the KEYMGMT of the |pkey| field if that
one is given (|pkey| isn't NULL) and is provided (|pkey->keymgmt|
isn't NULL).
