Downgrading EVP_PKEYs from containing provider side internal keys to
containing legacy keys demands support in the EVP_PKEY_ASN1_METHOD.
This became a bit elaborate because the code would be almost exactly
the same as the import functions int EVP_KEYMGMT. Therefore, we end
up moving most of the code to common backend support files that can be
used both by legacy backend code and by our providers.

This should have been publically present a long time ago, to be
consistent with the RSA, DSA and EC_KEY APIs. However, since we've
now deprecated that kind of function for the other key types, there's
no point in adding a public function, but we still need it internally.

Embed libctx in dsa and dh objects and cleanup internal methods to not pass libctx (This makes it consistent with the rsa changes)

This is required in order to share code for FIPS related parameter generation and validation routinues.
Note the 'counter' field is now stored as a integer (as that is the form required for generation/validation functions).
